Creating a flat of a vase
Creating a flat of a vase
(OP)
I am trying to take the surface profile of a vase and make a flat, but it is giving me heck.

A Gaussian surface is any surface which can be unfolded to a flat. Basically, this means cones and cylinders and flats joined in any combination along tangents.
There are programs that stamping toolmakers use to develop flats for non-Gaussian forms. They are not part of any CAD package. Toolmakers used to develop such flats experimentally, using sheetmetal marked with a pattern so that the deformation can be charted and back-solved.

It's been 2 years since I was on Pro/E. I do like to lurk in this forum to see what's up. Please excuse me if I'm a little behind the times.

Pro/E did not accurately form the hole pattern into the new complex shape. Rather it made the complex shape, and then projected the hole pattern onto it.
I don't know if this is relavant to your task, but it was interesting. Makes me less confident in flattening complex-shapes and getting an accurate hole pattern in the flat pattern.

The flat pattern shown no deformations or the like, though leading me to believe it is not very realistic.
