Of course Catchup always provides other options! Had also thought about using a cross section to produce the drawer box with follow me. Per attached. (Easy solution)
Then, just for my pleasure, draping the joint edge over the top of the corner? ( graphically pleasing) or
Creating a diagonal cut of the joint that I could then insert? And perhaps then trim so the joint projects thru the two components?
My intent was to create the front, back and two sides, with the top radius and properly showing the joint for each end as well as the kerf for the drawer base. I can visualize them but can't quite produce them
