Hi Michael (et al.)

In designing a cup with deceptively tricky geometry (the same one as 8 months ago...), I sometimes but not always have trouble joining the two surfaces - one is flat, the other is a nurbs-heavy sweep.

In the attached file, two versions of the cup smoothly joined all surfaces. The one in the middle will not.

Sometimes when I export as .stl or .obj and "repair" the file in netfabb, the gaps in geometry get fixed without a problem. However, most of the time, I get unfortunate artifacts like in the screenshot provided. These problems are best fixed in MoI so that the model doesn't need repairs, but I'm at my wits' end about how to do it. Please help!

The cup in the middle has the geometry I want. I can also get the geometry by just straightening the walls of the cup on the left (the one with concave sides), but I don't know a simple way to do that, and all the ways I've tried have resulted in the exact same surface-connection problems. Any ideas from other brains greatly appreciated :)

Thanks,

Yophie
