Bevel profile and even thickness

[marcatore]

hi guys,
I’ve a problem with the scene attached.
curve_sweep.zip (100.7 KB)

The problem is that when I try to bevel a curve using another curve, the thickness is not even in the corner or it creates a messy mesh.

The correct mesh I’d like to have it should be like this (made using 3dsmax)

Where am I wrong?
Is there something similar to the 3dsmax sweep modifier ?

It’s a pity that, as 2D curve, I’m forced to have the curve on the horizontal plane.

Anyone know an addon that has workarounded the problem with 3d curve?
I’ve tried this geomNode Z-Curve-Sweeper for Blender 3.0 (Curve-to-Mesh with superpowers) but without success

Hi, an update has been posed to the GumRoad file to fix even-thickness issues with Bezier curves. Thanks for your feedback.

In your case (i.e. using blender curve objects) there is not much point in using the Z-Up tilt option, as that is meant for curves generated from other things. Since you’re using a curve object you can use the Z-Up Twist Method instead (it will give exactly the same results): [image] Since all the Z-Up Tilt option does is what the Z-Up Twist Method does, you have to correct vertical sections in the manual fashion (same as you had to do with Z-Up Twist Method): [image] i.e. correct, generall…
