I don't use sheetmetal that often, but I usually build my part with square corners, and then insert bends. It inserts the cuts for me as well. Is this a good method to use when building sheetmetal parts, or is CBL's method better?
In this case I would build 3 extrusions. The far face, the middle span, and the near face. Then select the top face of the middle span, and click "Insert Bend" in the sheet metal toolbar. It adds both bends for me exactly as drawn in the picture.
I'm still using 2001+, so I am not aware of any improvements since.
