Technical note

3MF to IGS: what carries over and what does not

3MF stores a surface made of triangles, while IGS is built for exact solid geometry. The conversion has to derive surfaces from that triangle mesh, so the result is faithful to the shape but is not the same thing as a parametric model with clean features and editable dimensions.

3D Workflow

From mesh to CAD format

reaConverter converts 3MF models to IGS for CAD, quoting and archiving, a whole folder at a time.

  • Get each model as one IGS file that SolidWorks, Fusion or FreeCAD can open
  • Convert a whole model library in one run with the same settings
  • Pick up new models automatically with Watch Folders
  • Render preview images of the same models in a second run
