...just wanted to see how many of you guys use this feature to look for curvature contunity. Or are most of you at the point that you know just from your modeling techniques that the surfaces are smooth enough. This tool has been shown as an ID tool that was carried over from the automotive industry to see just how well light passes evenly across surface.
I use it (usually spherical map) and I use the curvature tool. Yes, knowing what the modeling functions does help but many times the on screen rendering/facets are not good enough, show strange distortions or the modeling controls (C2) do not work properly.
The question of "smooth enough" is interesting... I would say the majority of mcad users would only care about if the get a 32 finish and not really care about a curvature problem ever.
Anyhow, imho, the zebra and curvature tools help for my work.
My modeling techniques aren't anywhere near that good. I don't think SW is all that hot either, although 2005 should help (too far along in the project to risk changing right now, especially since some of the parts break).

I find zebra stripes to be kind of a pain to use, because the display is ambiguous. You have to rotate the model 'just right' to see the discontinuitites and issues.
To check for tangnecy, I use hidden line wireframe with 'tangent edges as phantom' - the feedback is instantaneous and unambiguous. Using angualr deviation tells you jsut how bad the non-tangency is.
To check how light plays across the modle, I bump up my image quality, make things specualr, and check it out with light. What is really nice is that you can tell whether defects are proud or depressions, neither of which is clear form zebra stripes or curvature display. It takes less rotation, and problems really jump out.
To check for curvature or glitches in surfacces, the curvature dispaly is champ. Again, you don't have to waste time rotating the model 'jsut right' and you can measure the curvature while you are in the mode.
