Do more with your 3D models

Opening CSM usually takes the program that made it. reaConverter reads it directly and converts models to STL, GLB, STEP or images.

  • Move models into STL for printing, STEP for CAD, or GLB and glTF for web viewers
  • Create isometric, top, front and side 2D projections as images or DXF/DWG drawings
  • Keep unreleased designs and client models on your PC: nothing is uploaded
