I’m modeling a railway for a staircase, so to start I’ve created a path for the rail itself, and a simple square (curve) to use as the bevel object (to be embellished later). The rail path consists of precise 90° and 45° angles. The problem is, when the rail path takes a right angle, the profile square gets smaller and tips a little, distorting the resultant object.
I’ve moved the center point of the profile object around… I’ve tried all combinations of spline type, twisting, path/deform settings, etc. on both curves… but I can’t seem to get it to give me orthogonal edges. If I make the railpath 2D, it works… but my rail needs to be a 3D spline. How can I fix this?
Edit: I just found this 4-year-old post calling out the same bug: https://blenderartists.org/forum/showthread.php?257000-3D-Bezier-Bevel
Is there any chance that someone has found a solution by now?
