PART 2 - The Bends!

I almost broke my brain looking at that backwards pic, until i scrolled a bit more and saw it was backwards

is that a plasma specific thing to do it inverted?

Sorry about that! And no, it's not a plasma thing, per se, I just simply extruded the wrong direction in Fusion 360, and did not catch it until later, and realized it would not make much difference if any, as I was going to be manually folding the box edges and would be sure to turn them the right way.

The only downside to cutting it with the backside facing up was that the side facing the water tray gets a bit more dirt and slag, so its clean up is slightly more involved. But a few seconds with chipping off slag and a few seconds with a wire brush attached to my drill and the underside was clean and smooth ready to become the upper side again! 

You should be able to select the reverse side and create a sketch. don't add anything.Then in the tree, right click on the sketch and export DXF.

You also do this with sheetmetal. Flatten the part then follow the same steps.
Sheetcam then makes it trvial to cut the DXF.

Yes, I simply grabbed the wrong side of the sketch, and then later realized it would not make much difference and did not bother with correcting it!
