Have a sheet metal disc, would like to put a hem around the edge... Any tips?
Things with developable surfaces. Which does not sound like a developable surface. (Such simple concepts drive jb nuts as he has no clues.) How would anybody actually make it? Curling the edge? Welding several bits? Drawing? Suggest model as several bits & then join them, if so.
originally you stated the hem was around the edge, that made it sound like the entire edge. so if it's only a tab you should be able to model.
I can't help, but there is an example on the SW Forum that should do it for you. It is in the Sheet Metal forum. The fellow who posted it is M. G. Martinez. It was posted on 4/24/2008. Jerry Steiger
