I am trying to unroll the attached object but am having problems with the the curved surface. It has been trimed and tweaked a number of times and finally mirrored. When I explode it I get six separate pieces. And I would of course want one so that I get my 2d shape in one piece.
I have tried merging the surfaces, but run in to problems beacuse previous trims have left edges unaligned.
I have tried deleting and rebuilding with a 2rail sweep, but the rail edges are also split in six, and I have not managed to merge them together.
Any suggestions on a walk around? I could of course piece the 2d pieces together, but I will probably be doing a few rounds of prototyping, so I would like to learn how to do this.
