Latest commit 008d7b6 Dec 20, 2016 @neomilium neomilium Fix "trying to encode undefined Unicode character" while opening project
For unknown reason, "filepath" variable is altered during HeeksCADapp::OpenFile() execution (only tested using wxLogDebug).

This commit attempt to fix most "trying to encode undefined Unicode character" errors using wxString instead of wxChar* when possible.

HeeksCAD is an open source, CAD application based on OpenCASCADE

Best known as the CAD in HeeksCNC ( CAD/CAM software ) see


  • Import solid models from STEP and IGES files.
  • Draw construction geometry and lines and arcs.
  • Create new primitive solids, or make solids by extruding a sketch or
  • by making a lofted solid between sketches.
  • Modify solids using blending, or boolean operations.
  • Save IGES, STEP and STL.
  • Printer plot the 2D geometry or to HPGL.
  • Import and export dxf files; lines, arcs, ellipses, splines and polylines are supported.

See here for instruction how to use HeeksCAD.


The solid modeling is provided by Open CASCADE. The graphical user interface is made using wxWidgets.

HeeksCAD can be translated into any language. There are currently English, German, French and Italian translations.


HeeksCAD has been built for Windows, Ubuntu, Debian, and OpenSUSE.

See the Wiki tab for details

There are packages for Ubuntu:

This means you can take all my work and use it for your own commercial application. Do what you want with it. It uses wxWidgets and Open CASCADE. Any changes to wxWidgets or Open CASCADE are subject to their licenses.


The best thing to do is use the discussion group:
