Technical note

What changes when you convert GLB to STP

GLB stores a surface made of triangles, while STP 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. GLB can hold motion as well as shape: a skeleton, keyframes or morph targets that move the model over time. STP 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 STP, and the model exists only as GLB. reaConverter writes it to STP in batch, offline.

  • Get each model as one STP 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
