Here are a couple of 5 piece doors that I recently did. All parts were Cut on a 3 axis 45. I wasn't able to design them with ecabs or use the door jig, but most anything is possible.
They go in a conversion "greyhound" type bus that I'm just finishing up. Lot's of fun and lot's of cussing!!!
I recently did some 1/4 round display cabinets (no doors) for a kitchen and used my CNC to cut the bending forms for the cabinet rails.
The CNC cut all the bending form parts out of 3/4" MDF in about 5 minutes and then I simply screwed them together. The next day I had perfectly shaped rails. I use plastic resin glue when gluing the 1/16" thick pieces of wood together as this has eliminated spring back problems I had with yellow or white glues.
It used to take me several hours to create the template pattern, bandsaw and route all the pieces and then assemble them. Now I have no problems with doing bent form lamination projects as the bending forms are created right from the original CAD drawings and TONS of time is saved.
The last time I did curved doors I used the barrel makers coopering method of gluing up boards then used a grinder and lots of sanding to final form and smooth the doors. They turned out pretty nice.
