I will continue to update the file as I develop the tool, hoping to add robust filleting and a print-friendly chamfering to relevant edges, facing some challenges on the fillets so far.
Sorry about that, here’s a version with internalized curves.
It is worth noting, in order for this to work each path MUST be seperate, as the end points of the paths are utilized for building geometry. The advantage to this is that it will also generate rounded “caps” for any non-closed curves.
