The following is a link to an alternative approach of how FreeCAD deals with minkowski requests, rather than use meshes the two Objects involved are converted to FreeCAD objects and colour coded, green (first), red (second). The idea is that users can then deal with the two objects in FreeCAD i.e. apply fillets, delete other object etc. i.e. The conversion should be more robust, but leave more work for the user in FreeCAD https://forum.freecadweb.org/viewtopic.php?f=9&t=43645 <https://forum.freecadweb.org/viewtopic.php?f=9&t=43645> -- Sent from: http://forum.openscad.org/
