Hi,
the curve bevel in object mode in Blender always sucked a lot because it was unable to properly create even offset profiles, unless one set the Shape type in curve to 2D instead of 3D, which was a dealbreaker. Ability to sweep any custom profile curve along any other custom curve is essential tool for most of architectural modeling, and one of the reasons archviz people often got frustrated with Blender.
I was hoping that GN would finally remedy this, and that the Mesh to Curve node would finally do this right. But to my surprise, the result seems to suck as much as the Object mode in the Shape panel of curve objects:
Am I missing something or we really can’t generate straight, even-offset curve extrusions with GN?
