I'm trying to import a STEP file to Blender, but it doesn't work!

This is how I do: I open the STEP file in Freecad and I select everthing, then I export it as a .stl file, but when I import the file into Blender, I only get parts of the object and some of the parts are in wrong position. Very frustrating and the client is waiting. I have also tried to export it as .obj and .dae file without any luck!

Can someone give me some advise how to solve this?

    $\begingroup$ First see if the file is truly exported corrected. View it in some online .stl viewer or in another software. If it displays correctly, try to convert it there to anything else and import in Blender. If there is problem with the file, the export from freecad does not work. There might be some problem with the model in freecad in that case. $\endgroup$ – Jaroslav Jerryno Novotny Dec 16 '18 at 22:09
  • $\begingroup$ Can you post the file or is it confidential? Try a free trial of Vector Works or Libre CAD. I had to try several different softwares until I found Vectorworks free trial. $\endgroup$ – ACopeLan Dec 17 '18 at 1:54
  • $\begingroup$ @JaroslavJerrynoNovotny I used a free trial version of moi3d and exported the object as a .stl file. It was very simple, fast and the result was perfect. But after 30-days it cost $295! I'm still looking for a free and simple alternative. $\endgroup$ – 3D-kreativ Dec 20 '18 at 20:32

You can use the STEP importer Addon, that was released for Blender 2.8x on January 27, 2020.

You may visit the support thread on Blenderartists. There you'll find the link to get the Addon, too: https://blenderartists.org/t/step-import/1203804
