Technical note

MD3 to IGS: what carries over and what does not

MD3 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. MD3 can hold motion as well as shape: a skeleton, keyframes or morph targets that move the model over time. IGS stores one static shape, so the result is a single pose and the animation itself does not carry over.

3D Workflow

From mesh to CAD format

A CAD system or a supplier asks for IGS, and the model exists only as MD3. reaConverter writes it to IGS in batch, offline.

  • Get each model as one IGS file that SolidWorks, Fusion or FreeCAD can open
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs
  • Convert a whole model library in one run with the same settings

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
