How It Works

reaConverter offers the fastest, simplest solution for converting your 3DS files into IGS without 3D or CAD software - all models processed on your PC for maximum privacy and speed.

Technical note

3DS to IGS: what to expect from the conversion

3DS 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. 3DS 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 3DS. reaConverter writes it to IGS in batch, offline.

  • 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
