Volume change after import to SolidWorks

Nur Kholish Majid May 29, 2017 8:45 PM

Hi Folks,

I got 3D Pro-e file from my customer and I can open it easily in SolidWorks. The problem is that when I measure the volume of the 3D Part in SolidWorks, It has different volume compare to measurement in Pro-e.

Any body know how to solve this and what is the effectt to the final product if then we want to create tool path and create the part in CNC machine...?

Thank You.

Did you run Import Diagnostics? Make sure all bodies are solid. Surface bodies do not have volume.

  Hi Alin,
  
  Yes, I did the diagnostics first...

not surprised.
..curious though.. what percentage difference?
..did you do a test of exporting as a parasolid (native) and open the parasolid.. any difference?
..and.. did you also do a round trip test (have your client test also).. save as a *.prt (pro/e, creo) (or export as parasolid or step... which ever works best for the pro/e users)... and compare volumes?

BTW.. what version are you using? 2017... the latest "3D Interconnect"?

  Hi Paul,
  
  I did several test and here are the different of the result:
  
  Part A: 0.00929% - File Size 500Mb
  Part B: 0.00265% - File Size 17Mb
  Part C: 0.00317% - File Size 24 Mb
  
  Is there any way to make the difference under 0.001?
  
  Thank You.

    You can adjust the accuracy level of the volume calculation:

      Hi Alin,
      
      Do you mean physically the actual 3D Data is exactly the same, but only matter of measurement accuracy that make the difference...?
      
      Thank You,
      Kholish

    0.001 of what?
    What are the actual volume numbers (including units) that you are getting?
    
    What is the manufacturing tolerance of the machine(s) that will be used to fabricate the part?
