Hi, does anyone know how to unwrap complex symmetrical surfaces in Rhino 6 or 7?
Simple symmetrical surfaces (curved in one direction only) are fine, but as soon as i try to unwrap a surface curved in multiple directions, even thou its symmetrical, unwrap produces asymmetric surface.
I’ve spent entire afternoon trying to model chair in multiple different ways and nothing helps, it doesnt matter if surface is one peace or multiple surfaces joined together… Any ideas how to solve this?
Since the resulting asymmetric UV Map unwrap fits the surfaces, how is this a problem?
What would having the UV Map unwrap be symmetrical too help you?
My guess is some sort of Rebuilding or Reparameterizing might help but you might lose the integrity of your surface shape too.
Sorry about bumping this but I also see this as a problem. Mapping a simple texture becomes a problem because it gets stretched or shrunk on one side compared to the other. For any symmetrical object you have to make both sides instead of just mirroring one. Would it really be so hard to make the UV map symmetrical? I certainly wouldn´t mind defining the symmetry plane. Working with SubD I actually already did that.
But Rhino obviously isn’t a texturing software is it? That being so what software do you use for texture mapping? Rhino failed me at 13th Decal so I’m looking for an alternative. 
Look at the Symmetrytip option in the Unwrap command. Also install Rhino 8 WIP if you can - unwrap is much better!

Rhino 8 is a huge step-up indeed. Also this thread is a good place to learn about it. Still there are some adjustments that could help I think.
