Seams/gaps in NURBS models: Maya vs Alias/Power animator?

[tmelr]

I'm trying to create animations that are similar to Alias Poweranimator ones with the Maya Renderer, but am having issues rendering nurbs. There are gaps and seams between surfaces that are adjacent. This is true for Planar Surface, Booleans, Trims, and Filleted Edges (created with the round tool). The only nurbs operations that seem to work seamlessly are fillets/blends.

Even a very simple boolean subtraction (a plane with a sphere ) won't render properly. Of course I expect seams with nurbs animation/deformation, but not with static objects! This seems to be the fault of the Maya renderer and the Maya's NURB tools, and how maya handles nurbs.

With Alias/PowerAnimator being more of a proper CAD program, I think it would be would be better at this sort of thing. (I know Rhino 3D is) Or was this also a problem with the old Alias renderer as well??

I can only go by Youtube videos and looking at the old versions of Poweranimator/Alias and there seem to be no gaps with trims and I'm pretty sure that the modern version of Alias wouldn't have this problem.


Maya trim:

Rhino 3D trim:

Maya round edge:

In any case, I think I will have use Rhino 3D for nurbs modeling instead and just use Maya for animation and rendering, and refining nurbs characters. (The blends/fillets in Rhino aren't animateable while in Maya they are)

Please let me know of any other advantages/disadvantages Maya renderer had to Poweranimator.

Thanks in advance.

Edit: With apologies, I no longer wish to have involvement with SGUG or SGI communities in general,
and have also chosen to remove all of my content. Many things have changed since I co-founded, named, and ultimately
then left SGUG. There are many good people around, to whom I apologize for frustrating by removing these things, and
also many petty people that over the years whittled down both the enjoyment as well as sense of obligation I used to
feel to anyone else regarding what was ultimately just a hobby. Unfortunately one of the latter now writes the rules
and so it is time for me to take my things and go.

This message will replace all of my previous forum posts because deleting threads that I started would have removed
other peoples' posts.

You can change the number of facets created, as well as smooth them out in Maya / PA. Look for some of the settings, I have never had this issue.
