NURBS Extrude
I've got a Problem with NURBS->Extrude.
I draw one Curve for the Path and a second Curve for the Path, like I've done it all the Time.
The Problem ist, that the Depth of the Curve isn't the same at all Parts of the Object.
Here you've a Screenshot of the Problem.

But to address the issue. There is no way to sweep that circular profile curve along that path and have a uniform cylindrical cross section.
It's physically impossible because the profile curve has to rotate at the corners and if you rotate the profile curve you change the cross section of the profile from circular to elliptical - hence the "loss in volume".
You would have to do the extrusions as a series of separate lofts or extrusions and then combine them afterwards.
