What I am trying to create is a range hood with slanted front that starts at 12"deep at the top and goes to 18" deep at the bottom with three raised panels on the angled face. Below the angled face is a ledge like a mantle with trim under it, and a curved raised panel valance below that. If this makes any sense to anyone besides me, I dont know. The cabinet needs to be 42" w x 32"h x 20" deep overall. Not sure how far off the top of the range the hood needs to be, at 32"h the panel would be 28" off the range.
