Sub D visualization issue

[edguydeaz]

I am having a problem and I can't find a way to solve it.

Working in Sub D environment everything is fine but at some point in the geometry I am working I need to move few CVs in Z, not a big issue, but when I do it in Hardware Shade mode and I move those CVs my model seems to "break" , patches look like if they not only moved in Z but in Y or X axis as well, (there is no history in the model, I deleted) the funny thing is when I go to box model everything looks fine but switching back to Hardware Shade mode seems is broken, making changes in box model is fine I don't see any duplicate face, edge or cv , nothing is unweld. 

I don't really understand what is going on here. I tried to copy that specific part into a different stage and is doing the same thing.

Has anyone experienced something like this? 

Thanks

This shouldn't happen. As it only affects the surfaces, not the control cage in box mode, I could imagine some kind of tolerance issues. Have you checked the size of your model? If it is rather tiny (e.g. a few milli-meters) such effects might happen, depending on your tolerance settings. You can try to decrease the 'Tolerance' in the lower part of the Control Panel to something like 0.01. Or work on a scaled version.

If that doesn't help, I could have a look on your file - if that is an option for you.
