Comments on Message 24 by Leonard Martin Struttmann <lenstruttmann@gmail.com> "1.The learning curve is steep, very steep. Even very simple parts can turn into disasters if one does not pay attention to the Topological Naming Problem. And when one starts to use parametric modelling, things get clumsy and tedious." FreeCAD user Realthunder has addressed the "Topological Naming Problem" his fork of FreeCAD Assembly 3 can be downloaded from https://github.com/realthunder/FreeCAD_assembly3/releases scroll down to Release notes and Assets. It is hoped that this can be merged into FreeCAD 0.20 at some point "2. The documented integration via the OpenSCAD workbench... doesn't work. My hope was to do 99% of a model design in OpenSCAD and then drop it into FreeCAD for the fillets and chamfers. However, I tried to import several non-trivial OpenSCAD models, none of them were even close." Chris Hennes is building test cases and we request that you post any problem files to https://forum.freecadweb.org/viewtopic.php?p=529071#p529071 Thanks!
