Looking for a simple (free/os) triangle mesh editor

[Eugen]

I need to 'draw' some simple 3D shapes for a new LDraw program I'm working on.

Its an old topic, but I would add Maverick Model 3D and Wings3D editor to the list:

• clover.moe/mm3d/ (source: Qt/C++ github.com/zturtleman/mm3d)
  
• www.wings3d.com/ (source: Erlang github.com/dgud/wings)
  

Few small freeware 3D editors:

• Pixie3D - https://pixie3d.com/
  
• Anim8tor - www.anim8or.com/smf/index.php/board,7.0.html
  
• Draw3D - https://draw3d.shervinemami.com/
  

Also, not a 3D editor, but CAD:

• FreeCAD (FreeCAD's Part Workbench has geometric primitives and mesh export is good).
  
• OpenSCAD (easy geometry scripting and good mesh export)
  
• SolveSpace (its easy to use, but exported mesh might be need to cleanup in MeshLab with few extra clicks).
