Im trying to repair a model airplane. I wish to make a disc that has rounded endges. Ive experimented with Filet and chamfer per youtube videos without much luck.

Hello - make a curve that has the shape of the cross section of the disc and make a surface from it using Revolve.

interesting tool, but i def dont have those drawing skills to figure it out.

was hoping a way to knock my sharp corners down. Im used to using illustrator for years, so all my approaches are based on those techniques.
