Technical note

GLTF to IGS: what to expect from the conversion

GLTF 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. GLTF 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

reaConverter converts GLTF 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
  • 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.
