Hi Bard, also another technique that you may want to look at for that kind of construction is a 1-rail sweep. When you sweep a profile along a planar rail with sharp corners in it, the corners will get mitered with each other making stuff like this:





That could build the side parts for some cases and then select the object and run Construct > Planar to build planar caps at the top and bottom to seal it off.

That can work for some cases but can also be sensitive to messy or fragmented path geometry as well.
