I'm stuck. Can't figure out how I can extrude a closed curve onto a NURBS curve without it looking tapered.
I notice that when it's set to "2D" there is no tapering, but I want to do it on 3d.
Thanks for help.

$\begingroup$ 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: devtalk.blender.org/t/… - Thanks in advance! $\endgroup$– BrunoCommented Jan 19, 2023 at 15:01

It's a known limitation of the current system, there is currently no elegant workaround for this as far as I know.
- Either use only separate 2D curves for each segment (rotate them in object mode to their correct positions)
- Add extra control vertex close to corners to minimize the tapering distance (clumsy and may not look good)
- Or use independent splines inside the same bezier curve for each segments (may cause intersection artifacts under certain circumstances)
Choose the lesser evil for your particular use case.

In the Object Data tab in the Properties panel (pictured in your screen shot), under Shape > Resolution: > Preview U:, change the number from 1 to 64 (the max). Leaving the Render U: at zero will cause it to use the Preview U: (just fine).
Also, make sure that you have added enough loop cuts to your cylinder so that it deforms properly.

2$\begingroup$ Hi Shady. I added resolution but no change. It still tapers. I wanted to be able to sweep a closed shape ( moulding ) into a curve. $\endgroup$– teebCommented May 26, 2016 at 13:47
