How to automatically place hole counts

John Pearson - Monday, June 19, 2017

 

We’ve had several calls, on our tech line, asking us if Solid Edge can automatically determine the number of holes in a part, and place that value in a callout. If you are using Solid Edge ST9, and the holes were placed with the hole command, the answer is yes. To achieve this, new Feature Reference Values were added to the Symbols and Values, in Solid Edge ST9.

 

To illustrate how this works, I will use the following draft document as an example:

 


 

I start by selecting the Callout command, from the Annotation group.

 


 

In the Callout Properties dialog, I select the Select Symbols and Values icon.

 


 

I first expand the Values section, and then expand the Feature References section, in the Select Symbols and Values dialog.

 


 

When I scroll down, I notice that 3 new values have been added to the list.

 


 

These new values will provide the quantity count for:

 

%QC – all coplanar holes of the same size and type.

%QP – all parallel holes of the same size and type.

%QA – all holes of the same size and type.

 

Continuing with our example, I highlight the %QC and hit the Select button.

 


 

Notice that a preview is provided, at the bottom of the dialog. I then click the OK button to return to the Callout Properties dialog.

 

Notice that the %QC value is placed in the Callout text field.

 


 

In the Callout text field, I continue by typing a space, the letter x, and another space. I then select the Diameter symbol and the Hole Size feature reference.

 


 

Note: Remember you can save this Callout text for reuse on other Solid Edge documents.

 

I click OK, to dismiss the dialog, and then select the 3 holes, shown below, to place the callouts.

 


 

Notice that only coplanar counts are given. I then repeat this process using %QP, as shown below, I get the following results.

 

 


 

Notice that the counts on the top view are identical, because all the holes reside on parallel planes.

 

 

I then repeat this process using %QA, as shown below, I get the following results.

 


 

Notice that the counts are identical for all 3 callouts, because %QA looks for all the holes in the part, regardless of their orientation.

 

In the previous example, I used the Callout command. I can also place these new values in the Modify Dimension Style dialog box. For example, I could place them in the Smart Depth Tab as shown below:


 

Then, when I use the Feature Callout option in any of the dimension commands, I get the same results as using the Callout command.

 


 

In closing, I’d like to re-emphasize, that these values only work on “like” holes that were created by using the Hole command. They do not work on cutouts. How does Solid Edge define “like” holes? Solid Edge looks at the following settings in the holes:

  •  
  • •Type
  • •Hole Extents
  • •Hole Depth
  • •V bottom angle
  • •Hole Diameter
  • •Chamfers
  • •Counterbores
  •  


     

     

    If these settings are the same for two holes, then they are considered to be like holes.

     

    If this, or any other information, in this article, is unknown to you. You may want to consider attending one of our 2-day Advanced Draft courses.

    More control over the tool axis in NX11.0.1

    John Pearson - Wednesday, May 24, 2017

     

    Two weeks ago, I had the privilege of attending a Cam Forum for Siemens PLM Software partners. A colleague and I drove down to Troy, Michigan, where we were introduced to new NX CAM functionality in NX11.0.1. We also saw some of the future enhancements coming in NX11.0.2 and beyond. Although there were many enhancements that I could discuss, there was one in particular that I found extremely useful. So rather than give a brief overview of all the enhancements, I will focus on one of my favorite enhancements. Once you’ve loaded NX11.0.1, open the help docs and view the what’s new section, if you’d like an overview of all the enhancements.

     

     

    Interpolate Tool Axis Enhancements

     

    Prior to NX11.0.1, if machining the part below, with the tool shown, you’d have a tool holder collision issue along the wall.

     


     

    When situations like this occur, NX now provides a new Control Direction option, when using the Interpolate Vector tool axis option. To access this new option, expand the Tool Axis section, in the operation template. With the Axis option set to Interpolate Vector, click the Edit icon.

     


     

    Notice the new Control Direction option under the Interpolation Method.

     


     

    The U and V option retains the behavior from previous releases. The U option controls the tool axis in the U direction only. The V option controls the tool axis in the V direction only. These two options give the new behavior.

     

    In this example, I’ll select the U from the Control Direction list.

     


     

    Notice the two iso curves. Each iso curve contains a system defined vector at each end. Only one vector is now necessary to define the tool axis along each iso curve.

     


     

    There is another new option, that allows us to select a system defined vector and tell the system not to consider it, when interpolating the tool axis. You do this by selecting the vector, and selecting the new Ignore Point check box. In this example, I first select vector 4, from the list.

     


     

    Note: You may also select the vector by single-clicking in the graphics display. Double-clicking reverses the vector direction.

     

    I then select the Ignore Point check box.

     


     

    I repeat this step for vector 2.

     


     

    Next, I select vector 3 and use the dynamic axis handle to rotate the tool about the YC axis, until the holder no longer collides with the part.

     


     

    The third enhancement becomes apparent will doing this rotation. In previous releases, the tool was rotated about the tool tip resulting in the tool cutting below the part surface. The tool now rotates about the contact point and no longer violates the part. See the image below.

     


     

    When I verify the tool path, I notice that the tool holder no longer collides with the part wall, but the tool axis begins tilting sooner than necessary. This is because NX tilts the tool axis continuously as it interpolates the tool axis between the two U curves.

     


     

    I can add another iso curve to control how long the tool remains vertical before tilting. To do this I return to the Tool Axis section and click Edit again. In the Interpolate Vector dialog, I select the Add New Set icon.

     


     

    Next, I select a point on the edge of the part, in the approximate position shown below.

     


     

    This defines an additional iso curve with a vector that can be used to control the tilt of the tool. By leaving the ZC vector vertical, the tool axis will remain vertical as it approaches the wall until it reaches this curve.

     


     

    This time, when I verify the tool path, the tool axis remains vertical until it reaches the added iso curve. It then begins to tilt as it approaches the next iso curve.

     


     

    As you can see from this example, you can now specify either a U or V control direction and ignore system defined vectors, allowing you to interpolate the tool axis for variable axis operations along U or V iso curves, with as little as a single interpolation vector for each curve. This capability greatly simplifies the task of specifying a constant tool axis orientation along the entire U or V curve.

     

    Working with Large Assemblies – Part 3

    John Pearson - Thursday, April 06, 2017

    In this article, I will continue to focus on some of the Solid Edge tools used to deal with large assemblies. As mentioned in the previous articles, “Working with Large Assemblies – Part 1 and Part 2”, If you are a Solid Edge user, hopefully you are aware of the following tools for dealing with large assemblies:

    •  
    • •Simplified Parts
    • •Simplified Assemblies
    • ○Visible Faces
    • ○Model Command
    • •Selection Tools
    • •Display Tools
    • •Queries
    • •Zones
    • •Configurations
    • •Limited Update
    • •Limited Save
    • •Assembly Open As options
    • •Assemblies made of synchronous parts.
    •  
    • Combine these tools with some best practices and other tips and tricks, and you’ll find that large assemblies behave more efficiently and are more reliable in Solid Edge, than any other mainstream CAD package.
    •  
    • In this article, I’d like to focus on the tools not already covered in the previous articles. To be specific, this article will discuss the following tools:
    •  
    • Selection Tools
    • Queries
    • Limited Update
    • Limited Save
    • Assembly Open As options
    • Assemblies made of synchronous parts.
    •  
    • Each of these tools offer the user improved efficiency and greater performance when working with large assemblies.
    •  
    • Selection Tools
    •  
    • All Solid Edge users know about the Selection Tool, but I have found many users are unaware of the other selection tools available in the assembly environment. If you have a look at the Select group, on the Home tab, you’ll notice that there are numerous selection tools available to assist you.

     

    The following list, briefly describes what each tool does:

     

    Overlapping - Selects elements which are inside or overlapping the fenced area.

     

    Selection Filter - Controls whether elements are selectable based on the element type.

     

    Select Visible Parts - Selects parts that are fully or partially visible in the active window at its current view orientation.

     

    Select Parts Constrained To - Selects parts that are constrained to one or more previously selected parts. This option is available after you select one or more parts.

     

    Select Subassembly Parts - Selects all other occurrences of the currently selected subassembly.

     

    Select All Identical Parts - Selects all the parts in the assembly which are identical to the selected part.

     

    Select Parts by Size - Displays a command bar, which contains a spin box so you can dynamically select a set of parts based on their size.

     


     

    The Part size field valueis based on the size of the parts in the current view where 1 is the smallest part and 100 is the largest.

     

    Activate PartAllows you to activate select parts.

     

    Faces Priority - Locates element types such as faces and features first, then other element types, such as parts and features. Used primarily for editing assemblies with synchronous components.

     

    Parts Priority - Locates parts first, then other element types, such as individual faces and features.

     

    Normal Select Mode Same as using the Select Tool.

     

    Add/Remove ModeAllows you to select multiple components. If the component is already selected it removes it from the selection set.

     

    Add Mode - Allows you to select multiple components. Can only add elements to the current selection set.

     

    Remove Mode - Allows you to only remove elements from the current selection set.

     

    Selection Manager ModeUsed to launch the Selection Manager, when an element is selected. See the Selection Manager menu in the Solid Edge Help, for more information about this menu.

     

    Clear Selection - Clears the selection set. You can also press the Esc key, or double-click in the graphics window to clear the current selection.

     

    Once you’ve created your selection set, you can perform tasks like Hide, Show Only, Inactivate, and Activate. Making these tools ideal for working on large assemblies.

     

    Queries

     

    Another method, for finding components, is to use the Query command. The Query command, found on the Select Tools tab of the PathFinder, allows you to search for components base on the component properties.

     


     


     

    Once you’ve used your query to create a selection set, you can perform tasks like Hide, Show Only, Inactivate, and Activate. Making this another excellent tool for working on large assemblies.

     

    Below is a quick list of other points regarding queries:

     

  • • You can define queries in an assembly document that is used as a template.
  •  
  • • You can copy a query from one document and paste it into another document using the commands on the shortcut menu.
  •  
  • • You can use the Query dialog box to specify whether you want to search subassemblies.
  •  
  • • You can also use the Quick Query option, on the Select Tools tab, to find and select parts in an assembly. Quick queries are not stored on the Select Tools tab.
  •  
  • •You can use the commands on the shortcut menu to edit, delete, and rename a query entry in PathFinder.
  •  
  • Assembly Open As options

     

    Over this series of articles, we have discussed how to activate, inactivate, hide, and show components. Above we discussed how to rapidly select components based on various criteria. Solid Edge also offers you a way to define what state you wish to open the assembly in. For example, you can open a large assembly much quicker if all the components are inactive, and even quicker if they are hidden. In the Solid Edge Options > Assembly Open As tab, you can define your definition of small, medium, and large assemblies. You can then define what state the components will be opened in.

     


     

    If necessary, you can override the defined settings when opening an assembly. For example, you can override the assembly size, on the Open dialog.

     


     

    You can even override the component state settings, by expanding the More.. button, on the Open dialog.

     


     

    Limited Update and Limited Save commands

     

    These are 2 relatively new commands, added in Solid Edge ST7. Added specifically for dealing with large assemblies, these commands are defined as follows:

     

    Limited Update - The Limited Update command confines updates to only those documents that, in the current design session, have been modified by you. If other documents have been modified by someone else, those changes can be viewed and updated by using the Component Tracker. The Component Tracker shows the status of these documents and saves can be made that overrides the limited save command if desired.

     

    Limited Save - The Limited Save command changes the behavior of Save when you work in the assembly environment. Selecting the Limited Save command confines the save operation to only those documents that you have opened and have write access to. Limited Save acts on documents in the current assembly structure. Processing is from the active level down. Part copies that reside in parent level assemblies are not updated with Limited Save.

     

    The Limited Update and Limited Save commands enable you to control, update, and save operations, while working in Solid Edge assembly, and while in-place activated. They need to be enabled on the Solid Edge Options > Assembly tab.

     


     

    When either Limited Update or Limited Save are enabled, PathFinder indicates the mode is active using an icon on the top level of the assembly.

     


     

    Before enabling these commands, make sure you read the Solid Edge Help documents, on these commands. They describe them in more detail.

     

    Assemblies made of synchronous parts

     

    There has been a lot written about the power of synchronous technology, in Solid Edge. The rapid modelling, and unprecedented speed of editing, has dominated these articles. But one of the often-overlooked benefits is that synchronous parts use less memory than ordered parts. Some of our customers are reporting up to 30 percent smaller assemblies. The smaller the assembly memory use, the better the overall performance.

     

    Summary

     

    This completes the series of articles on working with large assemblies. I’ve attempted to give you an overview of the more common tools that are available for improving your performance, and efficiency, when working with large assemblies, or any assembly for that matter. But let me emphasize that this was an overview. There are many more tips and tricks, methods, and commands that could have been discussed. For example, the recently added Isolate command, or the Insert Assembly Copy command, to name two. You can research more on this topic in the Solid Edge Help documents or attend one of our Advanced Assembly course. Where we teach all of the methods to deal with large assemblies, plus many more tools for creating, editing, and managing assemblies.

    Working with Large Assemblies – Part 2

    John Pearson - Wednesday, March 29, 2017

     

    In this article, I will continue to focus on some of the Solid Edge tools used to deal with large assemblies. As mentioned in the previous article, “Working with Large Assemblies – Part 1”, If you are a Solid Edge user, hopefully you are aware of the following tools for dealing with large assemblies:

     

    • •Simplified Parts
    • •Simplified Assemblies
    •     ○Visible Faces
    •     ○Model Command
    • •Selection Tools
    • •Display Tools
    • •Queries
    • •Zones
    • •Configurations
    • •Limited Update
    • •Limited Save
    • •Assembly Open As options
    • •Assemblies made of synchronous parts.
    •  
    • Combine these tools with some best practices and other tips and tricks, and you’ll find that large assemblies behave more efficiently and are more reliable in Solid Edge, than any other mainstream CAD package.
    •  
    • In this article, I’d like to focus on display tools, configurations, and zones. I’ll look at how they work, how to create them, and some best practices for using them. First, we’ll look at display tools.
    •  
    • Display Tools
    •  
    • One of the easiest ways to improve display performance, when working with large assemblies, is to control which parts in the assembly use physical memory resources. This can be achieved by inactivating components, hiding components and unloading components.
    •  
    • When you first load a part into the assembly environment, using default settings, the part is visible and active. That is to say that both the display data, and underlying math data, is loaded into the assembly file. The more components that are added the more data that is loaded. The more data that gets loaded, the more physical memory is used. The following paragraph is an excerpt from the Solid Edge Help document, and explains how available memory affects performance of the program:
    •  

    The amount of physical memory available on your computer affects the performance of all your Windows applications, not just Solid Edge. When the physical memory is completely allocated, some operations are swapped to virtual memory. Virtual memory is disk space on your hard drive allocated for use when physical memory resources are not available.

     

    Virtual memory is much slower than physical memory. When any application has to swap information between virtual memory and physical memory to complete a task, system performance slows down considerably. You can improve performance by increasing available physical memory in the following ways:

     

       Reduce the demand for physical memory

       

        Install additional physical memory in your computer

     

    Note

    See the readme.htm file in the Solid Edge folder for additional information on memory recommendations for Solid Edge.

     

    You can reduce the demand for physical memory in 3 different methods:

     

    Hide components: This allows you to unload the display data of the components. It also makes your display less cluttered, allowing you to work more efficiently with the displayed parts.

     

    Unloading Components: Once the components are hidden, you can unload them using the Unload Hidden Parts command. This unloads the part from memory, freeing up the memory for other tasks.

     

    Inactivate components: This allows you to unload the underlying math data on components, but still maintains the display data. You can see the component and the component will maintain any attached assembly relationships.

     

    Of course, if you hide a component, you can also show the component at any time. Likewise, you can activate a component when you need to perform any task that requires the underlying math data.

     

     

    Configurations

     

    When working with a large assembly, it is common to work on specific areas or sections of the assembly, at different times. Configurations allow you to capture and control isolated displays of those specific work areas or sections. For example, if you are working on a large vehicle assembly, you may want to focus on the rear wheel mechanism. You can inactivate, hide, or even unload, the rest of the assembly. Thus, only showing the components of the rear wheel mechanism. Then you can create a configuration, and call it Rear Wheel Mechanism.

     

     


     

    Once you’ve defined the configuration, you can use the Assembly Configuration list in the Home tab > Configuration group, to apply the specific display configuration. This allows you to quickly display, hide, inactivate, and unload specific components.

     


     

    Furthermore, when you open an assembly, you can select it to open to a specific display configuration.

     


     

    You can also place the configuration into a drawing view, by selecting it from the Drawing View Wizard options.

     

     

     


     

    Zones

     

    Zones are similar to configurations, but provide additional intelligence, to aid the user. A zone is a defined work envelope, which allows you to see either all the components inside the zone, or all the components inside and overlapping the zone. For example, imagine that you are responsible for the modeling of a conveyer belt sub-assembly, on a large machine assembly. Inside the large machine assembly, you can create a conveyer zone, as shown below:

     

     


     

    Like a configuration, you can display only the components inside of the zone.

     

     


     

    But you can also display any overlapping components.

     


     

    This provides the additional advantage of seeing any components that interfere with your zone, that may have been added by another user. Thus, making zones an ideal tool for large assemblies that are created and modified by multiple users. You also have the same added benefits offered with configurations, allowing you to open an assembly into a specific zone, and allowing you to place specific zones into a drawing view.

     

    Summary

     

    Display tools, configurations, and zones, are just a few of the tools in Solid Edge, used to accelerate work and improve performance in large assemblies. This article has been a brief overview of these tools. There are many additional options and benefits not covered in this article. Further information can be found in the Solid Edge Help documents, or you can attend one of our Advanced Assembly courses, where we teach all of the methods to deal with large assemblies, plus many more tools for creating, editing, and managing assemblies. The complete course syllabus can be found on our training page, at the following link: http://www.designfusion.ca//technical-training.html. Look for the third part of Working with Large Assemblies in the near future.

     

    Working with Large Assemblies – Part 1

    John Pearson - Thursday, March 23, 2017

    One of the most prominent issues, that has bogged down many CAD systems, is the ability to deal with large assemblies. Despite improved hardware and continuing CAD improvements, this issue is still a top complaint among many CAD users. In some cases, it is the CAD system’s architecture that causes the system to slowdown as the assembly size increases. However, with Solid Edge, most cases we encounter are the result of the user being unaware of tools and/or best practices for dealing with large assemblies. If you are a Solid Edge user, hopefully you are aware of the following tools for dealing with large assemblies:

     

     

    • • Simplified Parts
    • • Simplified Assemblies
    •      ○Visible Faces
    •      ○Model Command
    • • Selection Tools
    • • Display Tools
    • • Queries
    • • Zones
    • • Configurations
    • • Limited Update
    • • Limited Save
    • • Assembly Open As options
    • • Assemblies made of synchronous parts.
    •  
    • Combine these tools with some best practices and other tips and tricks, and you’ll find that large assemblies behave more efficiently and are more reliable in Solid Edge, than any other mainstream CAD package.
    •  
    • In this article, I’d like to focus on Simplified Parts and Simplified Assemblies. I’ll look at how to create them and best practices for using them. First, we’ll look at Simplified Parts.
    •  
    • Simplified Parts
    •  
    • Solid Edge defines a simplified part as:
    •  
    • A part that has had some of its features hidden using the commands in the Simplify Model environment. When you simplify a part, it will process faster in an assembly. You can control whether the simplified version or the designed version of the part is displayed in the assembly.
    •  
    • For an example of a simplified part, let’s look at the following part, which is the back of a clock.
     

     
    • Notice that this part contains, screw holes for attachment, and fill pattern of holes for ventilation. To simplify the part, you start by selecting Tools tab > Model group > Simplify option.

     


     

    This creates a separate header in the PathFinder, similar to creating a flat pattern in the Sheet Metal environment.

     


     

    You can now use the Delete Faces, Delete Regions, Delete Holes, or Delete Rounds commands to simplify your part. These commands are found on the Home tab, in the Modify group.

     


     

    In this example, the Delete Holes command was used to create the following simplified part. Notice the Delete Holes feature under the Simplify header, in the PathFinder.

     


     

    In the part environment, you can toggle between the two versions of the part, using the Tools tab > Modal group.

     

            

     

             

     

     

    When placed in the assembly, you can select which version you want displayed by using the shortcut menu in the PathFinder.

     


     

    This allows you to use the lighter weight, simplified version, in the assembly while you work. But you can easily toggle on the designed part for final display or any other time you may need it.

     


     

    Simplified Assemblies

     

    Similar to a simplified part, you can create a simplified version of a sub-assembly, to be used in the top-level assembly. Solid Edge provides two methods for creating simplified assemblies. Both have advantages and disadvantages, so it is up to the user to decide which will best suit their needs. Prior to selecting the method, you first have to tell the system that you want to create a simplified version of your assembly. To do this, go to the Tools tab > Model group, and select the Simplify option.

     

     

     

    Now you must select either the Visible Faces command, or the Model command, which are the two methods used to create the simplified version of the assembly.

     


     

    Visible Faces

     

    The Visible Faces command has the advantage of rapid creation of the simplified version of your assembly. The disadvantage is that it is not associative to the designed version of the assembly. When you make changes to the designed version, you have to remember to update the simplified version. Solid Edge defines the Visible Face method as:

     

    Creates a simplified representation of an assembly by processing the assembly to show only the exterior envelope of faces and by excluding parts, such as small parts. This improves interactive performance when you use the simplified representation of the assembly as a subassembly in another assembly or to create a drawing of a large assembly.

     


     

    Essentially, you create an outer shell of the designed assembly with the option to hide any small components, such as hardware parts, exposed to the outer shell. This is ideal for assemblies with many internal components, that are not visible from the outside of the assembly.

     

    Simplified Assembly Model (SAM)

     

    The second method is the Model command. This command launches the Simplified Assembly Model environment, often referred to as SAM. Solid Edge defines the Model command as:

     

    Creates a simplified representation of an assembly creating a solid representation of the simplified assembly. The solid model is stored as ordered solid geometry within the assembly.

     


     

    The SAM environment allows users to create rapid enclosure of the model, and then use ordered modelling to modify the enclosures to better represent the assembly shape. These simplified models are associative to the designed assembly. Plus, you can create simplified version of framed or cage like assemblies, that would be poor candidates for the Visible Face method. The disadvantage is that this can take a bit longer to create, than the Visible Face method.

     

    Using the simplified version

     

    Whichever method you use, the simplified version can be shown, in a higher level assembly, using the shortcut menu in the PathFinder.

     


     

    In the Solid Edge Help documents, under Controlling simplified assemblies, you will find the following table, illustrating the many ways to control simplified assemblies.

     


     

    It is important to note that simplified assemblies should only be made if it is a sub-assembly, of a higher-level assembly. Creating them will actually add weight to the assembly itself. However, you can significantly reduce the weight, of the higher-level assembly, when used in the higher-level assembly. Solid Edge best describes this as follows:

     

    Simplified assemblies and memory usage

     

    When you create a simplified representation of an assembly, the data storage requirements for the assembly document increase because the surface data for the simplified representation is stored in the assembly document.

     

    The size increase required to support the simplified representation is small when compared to the size requirements of all the documents that make up the assembly.

     

    When you place a simplified assembly document as a subassembly into another assembly, the memory requirements required to display the higher-level assembly drop dramatically. This improves performance and also allows you to work with larger data sets more effectively.

     

    This performance improvement also applies when creating a drawing of a simplified assembly. Because less memory is required to support the simplified data set, the drawing views will process quicker.

     

    Summary

     

    As mentioned in the beginning of the article, Simplified Parts and Simplified Assemblies, are just two methods of dealing with large assemblies. The intent here is to make sure you are aware of them and provide an overview of their benefits. The detailed creation and use, of these tools, require much more space than allotted for this blog. Further information can be found in the Solid Edge Help documents, or you can attend one of our Advanced Assembly courses, where we teach all of the methods to deal with large assemblies, plus many more tools for creating, editing, and managing assemblies. The complete course syllabus can be found on our training page, at the following link: http://www.designfusion.ca//technical-training.html. Future blog articles will provide further overviews of the other tools for dealing with large assemblies.

     

    How to Export Quality Images in Drafting

    Stephen Rose - Tuesday, January 03, 2017

    Introduction:

     

    • This FAQ explains the steps to generate quality shaded image views in drafting, including the use of translucency. 

     

    Requirements:

     

    • Understanding of Modeling and Drafting environments in NX

     

    Step By Step Process…

    •  
    • 1.Generate your solid body, or load an existing solid part, and adjust translucency as required.
    • 2.Switch to the Drafting environment and generate a sheet.
    • 3.On the top ribbon select the <File> Tab, then choose Preferences -> Drafting

     


     

    • 4.Under the <View > expandable menu select <Workflow>, then scroll down until you see the Visual Settings group in the right-hand pane.In that group check <þ> Use translucency and <þ> Use Line Antialiasing then select <OK>.(n.b. See end of document for anti-alias impacts)
    •  
    • 5.Place a view of your choice on the sheet drawing (the default will be a wire-frame view.

     


     

    • 6.Select the drafting view boundary, right-click and choose Settings
    • .
    • 7.For best results, in the left-hand pane, under the <Common> expandable menu select <Configuration> , and in the Settings group in the right-hand pane set preference to Exact Representation, rather than Lightweight.You can specify the curve tolerance here also.

     


     

    • 8.Now scroll down further in the left-hand pane and select <Shading>, and in the Format Group in the right-hand pane change the Rendering style from Wireframe, to Fully Shaded.Make any other adjustments needed for surface Shininess, then in the Tolerance group select one of the default Tolerances, or chose Customize to edit manually.Then click <OK>.

     


     

    • 9.You will then see results similar to this:

     


     

    • 10.You can then set other view dependent preferences if you want hidden lines, or smooth lines, shown different than the default setting.      Default

     

          Smooth Edges lightened

     

          Hidden lines processed

     

    • 11.Once your views are set you can use File->Export->pdf, you can use File->Print to a pdf, (with Export shaded views as wireframe left Unchecked), or you can File->Plot to plot to a suitable configured printer--or even plot out to a graphics format such as TIFF.

     

    n.b.Out of the Box the Graphic Plotting format resolution is set quite low.If you need a higher resolution you can go into the plotter administration and change the values.

    •  
    • 12.To set these Graphic Formats resolutions go to File->Utilities->Printer Administration, you are then prompted to Edit the printer setup or Create a new one.(See the Plotter Setup documentation for this initial setup.)Once you are in the Edit menu, you will see the <Graphics Default> tab, under that tab are the types of graphic formats for plotting to. You can edit each of their default resolutions here.

     


     

    Anti-Alias Notes in Drafting Mode:

     

    Anti-alias choices can make an impact on how well your shaded surface edges show up on the drawings.The two pictures directly below show the Drafting Preference setting “Use Anti-Aliasing”

     

      

    Use Anti-Alias Unchecked (OFF)               Use Anti-Alias Unchecked (ON)


     

    Adjusting Full-Scene Antialiasing toggle, can also sometimes improve results.

    Ways to help with Keyshot

    Cory Goulden - Wednesday, September 14, 2016

     

    Have you have ever been asked to create an image or snapshot for any reason and the model that you created in SE does not have the level of detail required? Maybe there are holes in a sheet that are not there (for performance reasons for example). Maybe a hose is just a tube but you want it to appear to have a ribbed type look to it? Keyshot might be the solution.

     

    We, as CAD designers, make a cognitive decision to keep things simple as best we can. Let’s take a look at how we can utilize Keyshot to do some of the heavy lifting in this case.

     

    We can start with a simple tube in Solid Edge. We need to produce a picture of this tube but it needs to look corrugated. Quickly we can take it into Keyshot. This is where the fun starts.

     

                  Start                                                                                                    Finish

     

          


    This is easily accomplished by using the thread face style in Solid Edge and then going into Keyshot.

     

     

    What’s that? Too easy or doesn’t look good enough. Okay we can apply a hard black plastic to it in Keyshot. That makes the cylinder look good but we need to apply a texture to it. On the left hand side of the Keyshot menu under the textures tab you can select the “Horizontal_Tubes_Normal”. As usual with Keyshot it is as simple as dragging and dropping onto our model. Next go to the right side menus of Keyshot and let’s edit the properties of this texture. From the Project menu under the Materials>Textures tab (As illustrated below) I changed the Scale to .1 and the Bump Height to 2. For this model those sizes give me what I want to see.

     

     

                            

     

    This looks great and I did not have to model the corrugation. A mistake some users can make. You may not need the information in the CAD model but you may need to show it in screenshots or documentation. Try doing it in Keyshot. I am sure you will have impressive results!

     

    “But you also said holes in a sheet” is what you are thinking now….I know I know. Great tools here too.

     

    For example, we design holes that have specific purposes. But let’s say we need a perforated sheet. We have a solid sheet in Solid Edge and take in into Keyshot.

     

    First option here is to apply a material type (such as “Aluminum Circular Mesh) to the sheet. This gives us circular cut-outs in the material. Again you might need to adjust the parameters. As you can see, you can see right through it.

     


     

    You could modify the colours from there is need be.

     

    You could also apply a Texture to an applied material as we did before in the above steps.

     

    This is a simple process to have fast performing models in Solid Edge and also be able to produce what might be required for presentations, documentation, or to others. Keyshot makes it easy!

     

     

     

     

    NX CAM: Eliminate wasted cutting motions on overhanging blank material

    John Pearson - Thursday, July 28, 2016

     

    Regular readers of our blog may recall my last NX CAM article, where I stated that many improvements to the software are missed due to lack of upgrade training. I gave several reason for this, which I’ll not repeat. If you’re interested, you can read the article: http://www.designfusion.com/designfusion_blog/nx-cam-options-for-selecting-cut-areas.

     

    Continuing on the theme from that article, I’d like to highlight another recent improvement that may have been overlooked by some users. This improvement focuses on eliminating some wasted cut motions. My old boss, back in my CNC programming days, used to always remind me that machine time was more valuable than my time. It was his way of saying that he wanted us to make our programs as efficient as possible. So I was trained to always look for cutting efficiency. Perhaps that is why this enhancement caught my eye. This was introduced in NX9, so if you haven’t upgraded to NX9 or NX10, you have to do this manually. Let’s first look at the scenario.

     

    I have a part to be machined, along with my defined blank geometry, as shown below.

     


     

    Let’s assume that I rough out the bottom of the part first, using cavity mill.

     


     

    Next I’ll want to rough out the top. I define my cavity mill operation and set the containment to use the IPW (in process workpiece). In other words, my blank becomes what was left after the last operation.

     


     

    The image below shows the blank material after the bottom rough cut.

     


     

    Prior to NX9, my cutting path would look like the following image.

     


     

    Notice that the tool roughed the top, but it continued to cut the bottom half which had already been roughed away. In NX9 they added an enhancement which omits cuts that remove insignificant amounts of material from overhanging IPW’s. So in NX9, under the Strategy tab, you will see a new option called Cut Below Overhanging Blank.

     


     

    If this is turned on, you will get the old pre-NX9 results, as shown above. If it is turned off, your path will generate as shown below.

     


     

    Notice here that no cutting motions are wasted trying to remove the IPW left behind by the previous operation on the underside of the part. This could add up to some significant machine time savings for your company.

     

    I will continue to highlight some of the newer NX CAM enhancements in future blog articles. But keep in mind that this is a slow way to learn about improvements. For example, had you attended an NX9 upgrade course, you would have learned this enhancement and more, almost 2 years ago. Imagine how much machine time that could have been saved; definitely enough to pay for the course and much more.
