Greetings:
Is there a way to project a curved sketch onto a sheet metal cone so that the sketch will "deform" with the cone when it is flattend? I found a way to do this on a cylindrical piece of sheetmetal, but it doesn't look like that method will work on a cone. The cone is a lofted bend feature. Thanks.
Just Extrude Cut the edge of your part through the cone. This will give you geometry that will carry over into the flat pattern. Then this geometry can be edited to "etch" instead of "cut" when the part is programmed.
