Hi steve, actually that is totally correct for this case - the whole point of that result there is to generate pieces that touch each other at the sharp corner in the rail.

The purpose of that particular model is not to make a tube that has a uniform cross section.

Read back over some of the posts in this thread, I have some explanations in there.

Geometrically, you can either have a totally regular shaped tubes with even cross sections in them that do not come to a simple miter-like joint, _OR_ you can have a non-uniform tube that does come to a common simple joint which it does by making a somewhat slanted shift to the sweep.

Just because something has non-uniform thickness does not mean that it is not "correct" if it is solving some other problem that someone has put a higher priority on, like in this case coming to a common angled profile.


If you think it is possible to have both a regular shaped cross-section, _and_ at the same time have the pieces meet in a simple common miter-like joint, then please show an example.
