I am trying to convert the attached file from a lofted solid to a sheet metal part. Seems like this should be pretty simple, however, I've failed at all attempts. What am I doing wrong? I tried to convert, but the model is missing a transition radius from the top to the sides, I tried to create curved surfaces which worked well, but I could not join the 5 sheet metal parts into one part that can be flattened.
Any help would be greatly appreciated,
