I cut the Pside cabinet doors today, bit of a challenge. I wanted enough material to hold it together. I cut off the bottom section flush to the top of the lower curve. Next I measured where the seam should be to make the height right. I added the width of the bottom section to where the inner plate should be and cut it. Then I cut out the upper section in 2 cuts, sparks flying as I cut through the nails. It works, a bit of glue and some fillers, sanding will do.
