Revolves using vectors look triangular

Anonymous — Tue, 05 Apr 2016 10:12:26 GMT

One of my revolves appear fine (on second try) and the rest appear triangular:

Actually, I see now that even the one I thought was fine, looks triangular when unshaded.

Anyone know what's wrong? Never used vectors before, but I believe I need it in this case.

Just found out that intersecting the revolve with another surface generates proper cos, but it crashes Alias on trim...

It's bad form to tack on a question, perhaps, but I did the revolve a different way (still using a vector), and stitch is now behaving in a way I've never seen before:

How is it possible that's it's not following the original surface (the blue line)? I killed all construction history before stitching...

eobet, thanks for reporting this bug. I can easily reproduce the triangluar look issue. Can you give more description of the crash? Thank you!

After selecting the revolve with the triangular look, use the intersect tool to produce cos on both surfaces of an intersecting surface and then attempt a trim on either surface.

I'm using Alias Design 2015 SP2.

Below you can find an example of the similar revolve stiching problem I posted about above, after I managed a work around to avoid the triangular look:

(Solidworks managed to stitch the surfaces without issue.)

Ok, I can reproduce it now.

Thanks!

Did you see the edit I made while you were posting about the stitching issue?

Yes, I can see it. I have reported two bugs about the issue. Thanks for your reporting.

Just a walk around: If you snap the end CVs of the revolve surface, the artifect on the surface will be gone. You can refer the attached video.
