The end product of what I’m making is a dome roof out of steel. It will be cut on a cnc plasma cutter and then the 8 rolled pie sections will be stitched welded to form the dome in the end. Before I get there I need to get a pattern from the wedge, and that’s where the unwrap and flatten extension comes in. And here is where I’ve hit my roadblock.
I’ve redrawn this several times and I can’t figure out where I am going wrong. The wedge needs to be a face so that the unwrap and flatten extension will create the outline so that I can cut this out. I’m assuming that it’s a coplaner problem, but I cannot for the life of me figure it out. When I drew up the dome I made sure I got the green dot that showed me that everything is connected. If someone can shed some light on this mystery I would greatly appreciate it.
