This article describes how to import CAD objects into OpticStudio, using STL, IGES, STEP, and SAT formats.

The choice of CAD format you use is likely to be based on the CAD program you use. STL is good for objects that are inherently faceted, or where you will use stereolithography to generate rapid prototypes. IGES and STEP are CAD exchange standards, and the choice between them will probably be based on the quality of your CAD program's export routines. SAT format will be used if your CAD program is based on the ACIS engine.
