Technical note

SKP to STEP: what to expect from the conversion

SKP stores a surface made of triangles, while STEP 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.

3D Workflow

From mesh to CAD format

reaConverter converts SKP models to STEP for CAD, quoting and archiving, a whole folder at a time.

  • Get each model as one STEP 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
  • Convert a whole model library in one run with the same settings
