In Marius Kintel's FOSDEM 2020 talk on OpenSCAD he discussed the challenge of Fillets with OpenSCAD.
Now in my experience I have seen people use the OpenSCAD minkowski command to create fillets. With the OpenSCAD
workbench use of minkowski results in the creation of a mesh.
Now the following is an experiment to see of the OpenSCAD importer can recognise certain minkowski requests and convert these to a Part
Fillet rather than a mesh.
Attached is a modified version of importCSG.py - You need to download it and replace the version in /usr/lib/freecad-daily/Mod/OpenSCAD.
Suggest you save the existing version as importCSG.save.
Here are the test files used todate.
The questions are
* Is this generic enough?
* Do people think this is worthwhile?
* Please supply other test files that you think should be handled but are not.
* Should a Part::Chamfer rather than Part::Fillet be used?
* With minkowski_B the "fillet" shows okay with OpenSCAD but the size of the radius of the sphere is too large for a fillet radius,
anybody able to explain what OpenSCAD is doing with this radius that makes it okay in native OpenSCAD
Note: I will be posting a link to this post in the OpenSCAD forum.
Thanks @felipe for his help todate.
