Anyone have a fast method of creating slot and tab construction for sheet metal weldments. Like is there some automated feature for selecting an edge and saying "I want 3 tabs spaced 10" apart along this edge". I currently do sketches and either extrude or cut. It is rather tedious to make all the mating slots and tabs around a 6-sides sheetmetal box weldment.

Any "slot and tab" macros out there?
