how to make curve bevel turning evenly?

Question

I use a square curve to be the bevel. With default settings. The result is like this.

More description:

My purpose is to make a bunch of foot line all around room. I want to use poly spline type curve to achieve this.

Without bevel object the curve geometry looks like this. The cross section is twisted at the corner which causes a shrink in the middle. Any way to prevent this?

could you give more context on what you are trying to accomplish? I'm not quite sure what you're trying to say — ETHAN DAY, Oct 27 '20 at 14:02
I guess your problem is that, on the top of the panel you're showing (the curve Object Data), Shape needs to be 2D and not 3D — moonboots, Oct 27 '20 at 14:10
hello is known issue from the curve modifier, i think this is related https://developer.blender.org/T40174 — Michael Ben David, Oct 27 '20 at 14:22
Thanks for the reply. More description are added in the post. I use 2d curve to be the bevel, even without bevel object, it behave the same. — bao007fei, Oct 27 '20 at 14:22
@moonboots Thanks for the help. I added a sample file in the post. — bao007fei, Oct 27 '20 at 14:46
@lemon what do you mean about '2d curve' exactly? They are just curves. — bao007fei, Oct 27 '20 at 14:55
as @moonboots suggested, the main curve has to be 2D to have the corner you want (not the bevel curve). But so the main curve is 2D only. — lemon, Oct 27 '20 at 14:57

Hi there, I am involved in addressing this issue in Blender. This is still in development but closing in on a solution and that'd be great if you could provide some feedback here: https://devtalk.blender.org/t/curve-to-mesh-node-even-thickness-feedback-thread/27271 - Thanks in advance! — Bruno, Jan 19 '23 at 14:58

Make the spine curve 2D is the key.
