Why is a push/pulled NURBS surface a tapered extrude?

[Bruce Kieffer]

If I create a NURBS surface and then use the push/pull tool to extract it, why is the resulting 3D object a tapered extrude rather than an extrude? I see no taper.

[Bruce Kieffer]

Hum, can anyone answer this for me?

I think its as simple as the Tapered Extrude command allows NURBS curves as the source shape and the Extrude command does not. It was probably the easiest way to integrate the Push/Pull command around the existing 3d solid types.

 

I used to use the Tapered Extrude command with a taper angle of zero a fair amount prior to the additional of the Push/Pull command. It accepts a few more shapes as the starting point (3d polygons for example).

This may be related.

I have a 3D polygon (but which is actually a flat surface, created from a 2D poly) at elevation 99850 (Z box reads 99850--see screenshot 1).

I click on the surface and push-pull to create tapered extrude

The base of the solid is unchanged, but now Z box reads 0 (see screenshot 2).

I'm sure I'm missing something simple--is anyone able to tell me what's going on?
