import geometries from other CAD software in standard exchange formats. Gmsh uses OpenCASCADE to import such files, including label and color information from STEP and IGES files;<br>

Can I edit STEP/IGES/BRep models?<br>
<br>
Yes: with the OpenCASCADE kernel (SetFactory("OpenCASCADE");), load the file (Merge "file.step"; or ShapeFromFile("file.step");) and add the relevant scripting commands after that to delete parts, create new parts or apply boolean operators. See e.g. demos/boolean/import.geo.<br>
