How to Calculate the Surface Area of an Assembly

John Pearson - Thursday, March 19, 2015

Calculating the surface area of an assembly can be useful for your manufacturing and other downstream applications. For example, knowing the surface area can allow you to predict how much paint you will need. This knowledge will allow your purchasing department to procure the exact amount of paint in advance, while also helping your company determine production costs.


Here is the method for calculating surface area:

 

  • Step 1. In assembly environment go to Tools tab and toggle on Simplify and then select the Button 'Visible Faces'.
  •  
  • Step 2. Ensure the option 'Analyze Assembly' is active and click on 'Process'.
  •  
  • Step 3. In the next ribbon select the option 'Copy Body' and then click on Preview and Finish. A simplified assembly model can now be found in the       Pathfinder.
  •  
  • Step 4. Select the Simplified Assembly with the right mouse button and save it as a part.
  •  
  • Step 5. Close the assembly and open the just saved Part.
  •  
  • Step 6. You should now see the Construction body and also a Toggle to Design Body, i.e. you will now have a closed Body, currently without any assigned material.
  •  
  • Step 7Assign any material to the body via the Application Button --> Properties --> Material Table, otherwise you will not be able to calculate the mass, volume and desired surface of the part.
  •  
  • Step 8. Go to Inspect --> Physical Properties and in the sub-menu simply click on the Update Button for a fresh calculation of the model.

 

The system calculates the mass (dependent on the material), the volume and the required surface area.
