Our client has provided us with a 3d model of a dome that they are building and asked to cut out the holes as required. What I want to do is create a 1mm sheet metal template with 5 elliptical holes in it that I can position on top dead centre and fold over on the dome so that we can scribe the holes and cut through precisely where they have to go. Where I am coming unstuck is that I can't work out a way to produce a sketch based on these holes, that I will be able to flatten out and export to the laser cutter.
Does anyone have any ideas or pointers? I've done a fair bit of googling but haven't come up with much. Attached is the solidworks part file.
