I am trying to create some pieces that have a slightly tapered surface. They are 24" long and I need the high spot of the taper to be 1" long and then from this point taper down toward each end by .03". Basically, I'm starting with .6875" thick material and I want to maintain that in the middle (for 1 inch) but need it to be .6575 on each end. Can someone point me in the right direction for how to do this in V-Carve or maybe some tutorials that would help with this? Thanks in advance!
