NX Draft Feature

Stephen Rose - Wednesday, July 29, 2015

Overview


Most users are familiar with the need to draft walls of parts or tooling to a certain angle. For those that are not familiar: It is used in manufacturing to allow de-mold of plastic parts and castings, a design requirement of some sort of functional fit, or so that the cutter and possibly the holder have clearance when machining down in deep-draw cavities.

 

The NX Draft Feature command has different sub-types when applying draft angle to a model.In this example we will use the two simplest types From Edges and Tangent to Faces types.

 

Where to find it

 

The Draft Feature can be found several ways.If you are familiar with the traditional NX menu you will easily find it under Menu->Insert->Detail Featureà->Draft

 

If you are more comfortable with the NX Ribbon style interface you will find it in HOME->Feature Group->Draft

 

There is always the command finder where you can search the Draft feature and access it directly.


Use


Here we have an unfinished (yellow) part with vertical side walls as our starting body.First we want to add a simple draft angle to the side walls.

 


 

We access the Draft Feature command, either from the Menu or the Ribbon Bar interface.

 


 

Ribbon Interface

 


 

Once in the Draft Feature:

 

1. We select Type of Draft from the drop-down list and pick From Edges.

 

2.We define the Draw Direction, in this case the Z axis.

 

3.We proceed to select the bottom periphery edge of the part.

 

4.We set the angle to 5° and then with the preview option turned on we see the model updates to having 5° draft around the entire edge.(NX is smart enough adjust the upper radii

without the need to remove the radii and reapply after the draft command.)We use OK to apply this draft and exit the dialog box.

 


 

With the body drafted we now want to add a Hole Feature.In this example we set the Counter Bore Diameter large enough, and the position of the hole far enough over, so that the Counter Bore breaks out the side of our body.

 


 

With the C’bore subtracted the resultant part shows that there would be sharp material conditions where the holes break out the side of the body walls.(Note: In this picture we have also mirrored over the feature for better clarity of the conditions)

 


 

We want to clean up this condition by straightening the C’bore surface so they end up breaking out 90° to the side walls.

 


 

We enter the Draft Feature once again:

 

1. We select Type of Draft from the drop-down list and pick Tangent to Faces.

 

2.We define the Draw Direction, in this case the axis must point away from the concavity of the c’bore-Y axis (not into it as +Y) as indicated by the orange arrow .

 


 

3. We then select the C’bore face that is to be drafted.

 


 

4.We set the angle to 0° and then with the preview option turned on we see the model update to having 0° draft to the axis, but starting tangent to the C’bore face.

 


 


 

After hitting OK to accept the draft we end up with the modified part body as shown.(Note: In this picture we have also mirrored over the feature for better clarity of the conditions)

 


 


 

This type of modification can be very useful in part/product design to clean up features and eliminate sharp corners in a mold. It can also can play a part in the tooling industry by opening up areas for milling machines. Opening up various break out areas on tooling can increase the amount of machining strategies available to complete a particular feature.In this case access to the side of the feature is now possible.Efficiency could be realized by allowing use of profile or other machining methods to complete the majority of this part, rather than having to mill down the vertical axis of the feature only.

How-to create a reference in draft from the assembly

Charles-Etienne Lavoie - Tuesday, August 12, 2014

How-to create a reference view in draft and keeping associativity to your assembly.

 

1) Place the assembly has you would normally do in a MASTER MODEL draft,

 

 

 

2) To create the individual views, return to the MODELING environment.

 

 

 

3) Open the exploded view menu




4) Orient the view to the desire position and save as

 

 

 

 

5) From the exploded view menu, select hide component to hide the unwanted part




6) Hide the component

 

 

 

7) You can use the show component in view to show component

 

 

 

 


8) Save the work view when done

 

 

 

9) To change the work view to a canned view, RMB in the work environment and select replace view, from there select any view or use custom for a more specific view.

 

 

 

10) Return back to the drafting environment and add the newly create view to your sheet

 

 

 

 

 

 

How to reattach a bolt circle and its dependent dimensions (Draft environment)

Frederic Menage - Thursday, July 31, 2014

Introduction

Draft annotations and dimensions rely heavily on their support geometry. Since it is possible with Solid Edge to attach dimensions to center marks, center lines and bolt circles; you have to know how to reattach those elements when the support geometry is replaced by another one.

Workflow

So, as usual, you have modified your 3D model and the draft file needs to be updated. After updating the view, a dialog called the ‘dimension tracker’ automatically opens (default setting).

First, you can classify the changes by clicking on the ‘reason’ column header. The changes and auto-reattachments can be validated and cleared (‘Clear Selected’ button) and you can then focus on the detached elements.



The Bolt Circle Example

The first thing you need to do is select the bolt circle itself (not the dependent center marks). It should highlight as shown in the image below and a quickbar should appear.


The two circles shown in red are still used as a reference (Note: the bolt circle was created using the 3 points technique). One of the three gray dots doesn't have a red circle attached to it. You need to reattach that third grey dot (beside #4) to the circle with the detached center mark.

By left-clicking on that grey dot (handle) and dragging to the circle (hole beside #4), you can “fix” the bolt circle. You can see (on the image below) how all the holes on the bolt circle are now shown in red when it is selected.


Notice how the dimension tracker is now showing only one detached element.


It is also necessary to reattach the center mark itself. Start by selecting the detached center mark as shown in the image below.


You can see that the bolt circle doesn't highlight (it is different from center marks that are correctly attached). Select the grey dot at the center of the bolt circle and drag it on the bolt circle itself (avoid other center marks and other keypoints). Selecting the detached centermark should now give you this result (bolt circle shown in red).


The second step is to reattach the center mark itself to the hole. Simply drag it (left click on gray dot at center) on top of the circle with no centermark.


Conclusion

What is important here is that we did not have to delete and recreate any object. We updated our drawing by simply reattaching the handles to the appropriate references.

Working With Revision Manager

Manny Marquez - Thursday, January 09, 2014

In the past few days, customers have called about revision manager and have asked several questions on how  they can move or copy assemblies to new locations.

There were a few main issues custumers have had in regards to Revision Manager, and what I have done is created multiple scenarios to tackle these issues .  

 

Scenario 1: Copy all assemly with all parts to new location.  

Scenario 2: Copy all parts associated to assembly and folder structure to new location folder.

Scenario 3: If a folder with parts related to an assembly gets nenamed  and links get broken, how to redifine links.  

 

Sample Folder structure (this can be any combination of folder locations) the point is that, we need to move or copy files to a new location.    

 

 

          Scenerio 1: copy all assembly with all parts to new location, this is ideal when you need to clone

          the whole asssembly to send to a customer.  

 

  1. 1. Open TOP level assembly with Revision Manager.

 

 
  1. 2. Expand then select all, this option makes sure that all files will be copied. Notice action is unchanaged.

 

3. Copy; this indicates the coping process.




4.The next step is to set the path for the new location to copy the whole assembly.

 

 

 

5. Final step is to perform actions. At this point the assembly is copied to the (new) folder location.
    However notice the subfolders are NOT copied.  This completes this scenerio.

 

 

   

          Scenerio 2:  Move the whole assembly with subfolder structure and related files only.

          Another method is just to copy all folders to the new location, but note that there may be

          files that do not relate to the assembly.

          In cases where you only need to move  files that relate to that top level assembly and keep the 

          same folder structure, files not related will not copy or move.  

 

6. Open selected assembly with revision manager.

 

 

 

7. We are going to move to (new location) and copy the same folder structure. By selecting the (rename)

    you are moving the files from the (original) folder.

 

 

 

8. Notice action is to rename document.

 

 

 

9. Now click on replace old folder (Original) with new folder (New). Then select replace all then cancel.

 

 

 

 

10.Once replaced, see new folder with new location.

 

 

 

11.Click on Yes and close Revision Manger.

 

12.Notice the new folder structure in new location, notice the subfolders are copied as well.

 

 

 

13.Review new folders using window explorer to take a look at the previous folder location; notice only

     files that were not associated to the assembly did not copy (This is also a good way to isolate

     assemblies) with the folder structure. This complete this scenerio.

 

 

          Scenario 3: Cases when a folder gets renamed and then you open the assembly and notice that

          all links are broken. This is very common in networks with many users.

 

14.So let’s go ahead and rename each folder as shown below, just by adding “1” at the end of each

     word.

 

 

 

     If you try to open the assembly now with RM or Solid Edge, the files will not open; you will get a notice

     that files are missing.

 

 

 

15.Click on the redefine links then select top level folder then ADD (make sure that the subfolder is

     unchecked).

 

 

 

16.The easiest way to get the folder address correctly is by going to the window explorer, and then copy      and paste.

     -(ManufacturedParts) is the original folder

     -(ManufacturedParts1) is renamed folder

     -click next twice

 

 

 

17. Click on Back twice  

 

 

 

18. Repeat for other folders

 

19.Next twice

 


    Close Revision Manager, and then reopen with top level assembly. This completes this scenario.

 

    This was also presented at one of our Solid Edge Productivity summits by Barry

    Shillingford.



How to create an adjustable coil spring in synchronous

Manny Marquez - Wednesday, October 30, 2013
In the September 18th  blog, we showed you how to create an adjustable coil spring using the Ordered/History modeling techniques. We can take different approches as to how to model this spring. We can use helix or wrap sketch techniques, but that doesn’t mean we can make the spring adjust using ST. In the following steps, we will take a look at how to model the coil spring using  ST modeling.

1. Create all sketches as needed. We will start with sketching path for all features.



2. Select sweep. We are going to use the Twist option


3. At this point the twist option is not selectable.



4. Select the path then accept.


5. Then pick on the cross section.


6. After selecting the cross section, you will get this message. It’s Ok, just click on EDIT, and then edit definition.


7. Notice that the Twist option is now available. For the first feature select number of turns of (-1.0)


8. This is the result.


9. Next, repeat the same step for the opposite side, using (1.0) for the number of turns.


10. Click on sweep protrusion.


11. We will now create the extended protrusion out from the twist using a single path.  Select options as shown click ok. Then select path and accept.


12. At this point select the cross section.

13. Repeat step for opposite side.

14. The next step is to create a revolve protrusion about an axis; we need to draw a line offset from the center of circle. Lock plane then (ctrl+H) this will allow viewing normal to surface


15. Draw a line .032 from the center of the circle and add a perpendicular relationship from the 33˚ line.


16. Select the end surface; then drag the steering wheel to the line created from the last step. Snap into the line so the torus is perpendicular to the line.


17. By selecting the torus then selecting the (lift) option on the ribbon, this will allow the surface to rotate about the center line. Enter 70˚ or appropriate value.

18.  In this step there are two options. (I used option 2)
1. Click on the protrusion command select surface as indicated, enter value.
2. Select the surface as shown, use the lift option and drag .300 distances.

19. Mirror features for opposite side.



20. This portion is a very crucial step in order to make this Synchronous part coil deform   
 as the part adjusts.

I’m going to show you two options to adjust the coil spring.

OPTION 1
Select every surface/ feature, except the two as indicated with red arrows; drag the steering wheel to the coordinate system. The torus must be parallel to the direction in which to rotate the part. (See image)
                 (Do not include any of the sketches to rotate along with the part.)

21.  Select the steering wheel torus, then dynamically rotate the part or enter a value.
   (Notice the two surfaces that were not selected stay stationary.)
You can repeat these steps at any time if you wish to adjust the coil.

Remember what value you use. This will be helpful, if you need to change it back to original state.

FYI:   If you decide to finish the model, then try to rotate to adjust coil spring angle,   this will not work. ST will not allow you to dynamically drag angle from both ends, only   one at either end.

OPTION 2

22.  Select the circle command and lock to Base plane to create a circular cutout.
  (ctrl+H)

The idea behind this is to have live rules recognize the concentric cutout; this will    prevent the coil from moving about the center when we later add an angular   dimension.

(The Diameter size should be minimum size possible as long as it cuts into coil without making an impact on your design intent.)


23.  Select the symmetric extrude and remove options from the smart ribbon bar.
 (You can use the space bar to toggle between add or remove)

24. Add an angle between dimension, select the (y) axis vector from the (UCS) then place dimension.   ( See images)

25.  At this point select all surfaces except two as indicated with red arrows.
RMB click to create a user-defined set.

26. The next step is to select the (a) user-defined set. 
Then click on (b) angular dimension to start modifying the angle.

27. As you can see, by dynamically changing the value, the coil is changing and adjusting. Notice the center cutout stays concentric to the center of the UCS origin. That was the only reason to create that cut out, so that live rules recognizes this predictable behavior.

You can repeat these steps at any time if you wish to adjust the coil.
Remember what value you use. This will be helpful, if you need to change back to original state

28. You will create the last feature using the sweep command.



Select path then cross section.

        (This feature will not rotate or adjust like previous modification.)


  Results



Note: 
For future modifications you may need to restore sketches, to use when deleting the feature to reuse after modification is made. In other words, if you need to change the angle, you have to: 
   a. Delete feature.
   b. Restore sketch.
   c. Rotate, modified angle.
   d. Add feature again.

29. Fence select all parts (except sketches), hit (Ctrl +R). This will allow viewing from right view.

30. Drag steering wheel to coordinate, snap so that torus is parallel to rotating angle.
Dynamically rotate or enter a value.

31. Keep in mind, if you need to modify like in step 19 or 21, delete feature.









Ordered vs. Synchronous – Which should I use? – Part 1

John Pearson - Thursday, October 10, 2013
  1. I’ve been approached by many Solid Edge users who ask me if they should be using the synchronous or the ordered method for the designs. I always answer yes. To which they smile and usually ask “No, really, which is better?” To which I respond, why choose? Use both. This may seem like a political answer, but it’s not. The true power behind Solid Edge is the hybrid approach utilized through integrated modeling. To understand the benefits, we first have to look at the pros and cons of each paradigm.


Pros and Cons of the ordered paradigm


Ordered modeling has been in Solid Edge since day one. It is like an old friend that many long time users are comfortable with, and experienced in. Many of the users I talk to claim that they like the control that ordered modeling gives them. Ordered modeling forces the user to build the model in a certain order of steps, which are predefined by the intent of the designer.

For example, the designer starts with the sketch or profile for his/her base feature. He/she draws the profile and constrains it with 2D geometric and dimensional constraints. By doing this he/she is controlling how the sketch can change. This involves some thinking ahead and predictions of potential future edits. 

Once the sketch is complete, it becomes the parent of the base feature. In other words the sketch drives the base feature. Additional profile base features are then added to the base feature in a similar manner. Each becoming a child of the base feature, thus creating an ordered structure that is shown in the Pathfinder. Treatment features are then added, creating more parent child relationships, until you have a completed model.

The ordered structure appeals to a lot of designers. Especially, if the design lends itself to a master model approach, where you create a master model and then generate many variations off that model by simply changing a few parameters. This does require intelligent set up of the master model and a good understanding of how the model was constructed.


So when I ask my customers what they like most about ordered? I get the following list of Pros:

Very structured approach to modeling.
Predictability to the designer who created the model.
Ability to lock down how the model behaves.
Other users can’t accidentally change my design.
Easy to set up family of parts or family of assemblies with a master model approach.
Long accepted method of modeling with a proven track record.  
Creating the initial model is just as fast in ordered as it is in synchronous method.
I am use to ordered design and have lots of ordered legacy data.

From a designer’s point of view, all these are good reasons to stay in the ordered paradigm. However when I look at the list, I get a feeling of déjà vu. It looks very similar to the list of reasons that designers use to give for staying in 2D. But we all know that many companies have switched to 3D. Why? Because the industry recognized that switching to 3D design provided many advantages. In other words there were a lot of Cons in 2D design. So what are the Cons of the ordered method?

It should be noted that some of the Cons or disadvantages that I am about to list come from working with the synchronous technology for almost 6 years now. Many designers will disagree with some of these because they do not have a true understanding of how synchronous modeling works. So with that in mind let me list some of the main problems with ordered designs.

Forced structured approach to modeling.
Modeling requires the designer to predict how the model could change in the future.
Editing the model is slow and cumbersome if the designer incorrectly predicted the

        future changes, or uses the part as a reference part to initiate a new model.
Making changes requires an in-depth understanding of how model was originally  

        created.In some situations it has proven faster to re-model the part then to try

        and understand all the parent-child relationships.
On large models, re-compute times can be lengthy due to the structured approach.
Models are heavy because of all the history saved in the part files. This makes opening and saving times lengthy.
Working with foreign data can be a challenge without the history/feature tree.

I’m sure my colleagues, could list a few others, but I think that these are the main ones. The next question then becomes how can synchronous eliminate or minimize the problems we face in ordered, and is it enough of an improvement to start using synchronous modeling? To answer this question, let’s look at the Pros and Cons of the synchronous paradigm.

 


Pros and Cons of the Synchronous paradigm


If you believe the marketing from Siemens, they claim the following:

“Synchronous technology provides the first history-free, feature-based modeling technology that enables up to 100 times faster design experience.”


Let me clarify this statement. It is not saying that all your designs can be done 100 times faster. In fact, if you start a design from scratch, the initial design process may only be slightly faster in the synchronous paradigm. However, there are aspects of the design process, which are up to 100 times faster if not more. Synchronous takes advantage of today’s powerful computer processers, and the elimination of Parent-Child relationships, to allow fast flexible modeling. Yet, with tools such as Live Rules, Procedural Features, 3D driving dimensions (PMI), it still provides the designer with control over the design when needed. So let me give you my list of synchronous Pros:

Rapid, flexible design tools.
The designer does not have to predict how the model will change in the future. 
History free approach allows for instantaneous model changes while editing the model.
The sketch does not drive the model. The dimensions are migrated to the model and directly drive the model at the 3D level.
Rapid edit tools and handles allow the designer to edit the model without having to understand how it was originally modeled.
Can edit a part file or group of parts from the assembly level, without having to edit into each part.
Can edit models from any CAD system as easily as editing solid edge models.
Model can be constrained at the 3D level, but not really necessary.
Models are lighter therefore open and save faster than in the ordered paradigm.
Can convert legacy ordered models into synchronous models.  
Although a different approach to modeling, it shares many similarities with the ordered paradigm. Thus easier to learn for existing Solid Edge users. 

Given all the Pros, you may be asking why everyone hasn’t changed to synchronous modeling. I believe that there are a few reasons for the hesitance to change. The first is the way Siemens introduced synchronous technology. It was first launched in the fall of 2007 in Solid Edge ST. It was new, and limited to part modeling with no real tie in to the ordered parts. Many users tried it then, but were left unsatisfied due to the limitations. The following year Solid Edge ST2 was released and introduced synchronous sheet metal modeling.  But again there seemed to be two separate paradigms with limited connection between the two. This all changed with the release of ST3 which introduced integrated modeling, allowing users to combine both paradigms within the same part. Unfortunately, many users had already made up their minds based on their less than successful attempts with ST and ST2.

Another reason for resistance is lack of training. Too many companies fail to see the benefit in properly training their users in the synchronous paradigm. They expect the user to pick it up on their own, while maintaining the same level of output.  It has been my experience that this approach fails most of the time. Designers may attempt to learn it, but will often revert back to the way they know, in order to meet company deadlines. The user will often resist the change for no other reason than lack of time to properly learn it.


The third reason is that there are some definite limitations in synchronous modeling. Certain features or techniques behave better in ordered because of the nature of synchronous modeling. I list the main Cons of synchronous modeling as follows:

Certain features have limited editing capabilities and are handled better in the ordered paradigm. Some examples include:
o Swept and lofted features 
o Certain rounds and blends
o Surfacing
Dangling bends are not currently supported in synchronous sheet metal. This limits

certain functionality.
Training – users need proper training to understand the synchronous paradigm. 


Some users may believe that they have more control in ordered, but that is a myth, based on lack of knowledge of the synchronous modeling tools. I will explain this more in my next blog article. But let me finish this article by discussing the integrated modeling approach.


Pros and Cons of the integrated modeling approach


Solid Edge allows the user to start the design in the synchronous paradigm and add ordered features if necessary. This approach allows the user to utilize the best of both paradigms. The synchronous portion of the model becomes the parent of the ordered features. This allows the user to change the synchronous parent which triggers an automatic update of the ordered dependent features. Furthermore the assembly can be populated with ordered parts, synchronous parts, and integrated parts. 


The only Con for this approach is that the designer has to be trained properly.

In my next blog article I will continue this article and further discuss the reasons why  customers are resistant to changing to synchronous technology. I will show how these perceived reasons are based on myth or inaccurate information. It is my hope that after reading both these articles you will have a better understanding of synchronous technology and be willing to take a second look at how it can be integrated into your design process, saving you time and money.
