Technical note

What changes when you convert IGS to OBJ

IGS holds exact mathematical surfaces and OBJ approximates them with triangles. Curves become faceted, and how visible that is depends on the level of detail, a value from 1 to 7 in the 3D formats loading settings. A middle value suits most printing; for a close-up render of a shiny curved part, raise it and expect a larger file. IGS records the unit its model was built in, and OBJ has nowhere to put one: it holds bare numbers, which slicers read as millimetres. A model built in inches can arrive 25.4 times too small, one built in centimetres ten times too small. Check one known dimension in the slicer before printing.

3D Workflow

From solid model to mesh

Need IGS parts on a printer, in a slicer or in a web viewer? reaConverter turns them into OBJ meshes offline, a whole folder at a time.

  • Set the level of detail from 1 to 7: finer triangles for smooth curves, fewer for small files
  • Script the job from the command line for pipelines and scheduled runs
  • Render preview images of the same models in a second run
