I'm a sheet metal newbie and I'm trying to design a leaf style landing gear. I've created multiple coincident closed surfaces that I would like to "extrude" to 0.125in thickness. I know that I could have created a base flange and then made flanges coming out of that but it is inconvenient from a design standpoint. So is my workflow totally wrong? The problem some of my flanges are not rectangular and making a rectangular flange and an extruded cut seems a rather bad way of doing it, especially if I want to make changes. Thanks for your advice!
