Technical note

GLTF to IGES: what to expect from the conversion

GLTF stores a surface made of triangles, while IGES 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. IGES 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 IGES, and the model exists only as GLTF. reaConverter writes it to IGES in batch, offline.

  • Get each model as one IGES 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
