Technical note

What changes when you convert X3D to IGS

X3D 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. X3D 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 X3D. reaConverter writes it to IGS in batch, offline.

  • 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
