3D Modeling & CAD – Frequently Asked Questions

What 3D CAD modeling software does PartSnap support?
PartSnap maintains active, current licenses of SolidWorks, SpaceClaim and Rhino 3D CAD modeling software.  Using a suite of translators, we can easily import and work with 3D CAD data from any major CAD system.
How do I save my CAD design to an STL file?
To convert your CAD file to an STL file, in most CAD systems:

  • Go to File, select Save-As or in some systems select Export to CAD
  • From the filetype drop-down menu, select STL (*.stl)
  • Select the Options button to adjust the resolution of the STL export
  • Within the options menu, select Binary Format (instead of ASCII)
  • Within the options menu, adjust Surface Deviation to o.001 inches
  • Within the options menu, adjust Normal Deviation to 4-degrees
  • Enter your file name and select SAVE. You now have a file type the printer can read

Or, more simply, you can send PartSnap your CAD file and we will complete this conversion at no additional fee. It is just one of the many perks we offer our 3D printing clients.
