For a round furnace i am making sheetmetal drawings. My way of doing the shell is
First,create round shell,insert holes for nozzles,then inset bend,extract flatten drawings..
Problem is since the holes are distorted after inserting bend,in drawing i dont get centre point to locate position of holes.I am drawing reference axis on flatten sheet then using that sketch for dimensining..Is there any other way to do this automatically? If not SW can add a new feature where we can get reference centre point for holes.
