Well, my model doesn't even represent my intent yet, and it's an utter mess. I wanted advice on how to set this up properly, with the idea of starting over.
I want a standard corner item, and three wall items of different lengths. But I have only created one wall so far, because I haven't figured out how to make walls of different lengths. I also created a specialized fourth wall in a way that it gets completely messed up when I change the wall length. For now, I have to change wall length, and then export the stl for an item that length. Which is not ideal, as I'd like to assemble the whole thing, and it's impossible without the different length walls. The lengths for longer and shorter walls are in my user parameters under shortWallL and longWallL. I made a sketch showing the shape I indend to have when I'm done. The long and short walls have slots, the medium wall does not.
But fwiw, here is what I have. (The walls are divided horizontally because my printer has adhesion issues printing the whole height...)
EDIT: As typically happens, in the course of formulating a more precise explanation of my problem, I hit upon a solution. In fact I can think of two:
1. Create a half-sketch with all three wall lengths represented. Extrude different length profiles to new components. Mirror these.
2. Create a half-sketch with the shortest wall length, extrude vertically, then extrude horizontally to new components.... could I get three distinct different-length walls this way?
