I have a sheet skin flat pattern with cutouts that need to be rolled to a 76 inch radius, is there any way to project the flat pattern onto a 76 inch radius surface keeping the true (geodesic) profile and cutout lengths correct??
I *think* I know what you are trying to do and I have done it a lot with sheetmetal parts. I have generated some pretty wonky laser-cut flat-patterns of rolled snow plow moldboards, and it seems to work just fine.
Try the following: Start with a rectangular sketch where L = (pi)*76*2. Then use Insert-Sheet Metal-Base Flange. Put in your punched holes and cutouts. Start a sketch and put a vertical line across the middle of the flat part face. Finally, Insert-Sheet Metal-Sketched Bend and change the radius from `default' to 75.9999...., and change the angle from 90 to 359.
Your cutouts will be slightly distorted in the rolled state, and straight in the flat state. If that is not your intent or manufacturing process, start with smaller circle cutouts instead, then after the Sketched Bend has been added, use the temp axis or centers of the small holes, to place and align new cutout features of the correct size, to the locations.
