Traceparts Online Parts Library

Grabcad Parts Library

Acceptable file types include the following: step, iges, stl, dxf, dwg, obj, and certain Solidworks files. 

  5. I’m unable to view and or open the CAD file sent to me from ISS.  What can I do? 

Answer: Please check your graphics card to make sure it’s powerful enough to process the visual imagery of the CAD file.

Answer: There’s plenty of free, safe, and easy to install CAD viewers.  Here’s a listing that you can choose from depending on your computer’s operating system:
