GrabCAD Library mentions (24)

  • We rendered and embedded one million CAD files
    Interesting. My go-to for CAD files is usually https://grabcad.com/library. - Source: Hacker News / 5 months ago
  • Where can I download 3D models?
    Grabcad is a good resource. For parts that are highly standardized you can find a library for all DIP ICs, Pin headers, TO-220 etc. For stuff like capacitors there are so many sizes that it is unlikely to find an exact match at grabcad. Source: over 2 years ago
  • Is there a FREE STL file for a t8 Torx head?
    You're not very likely to find an STL file, but it would be easy to find a STEP file which any decent CAD program could convert to STL. Take a look on https://grabcad.com/library. Source: about 3 years ago
  • Anybody willing to teach 1on1 online?
    Ok some things here. Stl does not works well with fusion360, you'd be better off modifying it with blender check this video) If you want to use fusion try to find a similar file in STEP format or IGES the best place to find it from is Grabcad. If you really want to import your stl into fusion 360 here is the way to do it properly And to finish up you NEED to give more info to get help, I know you're scared someone...

  • Iโ€™m needing to make a 3D rendering of a piece of machinery.
    If it is commonly used you might find the parts here. https://grabcad.com/library. Source: about 3 years ago
