I really could use some help. I have a job that requires me cutting alot of different compound angles in 3/4" thick mdf panel. What I'd love to have is a sort of universal assembly basically consisting of 2 virtual wood panels where I can change the slope angle of each side as well as the corner angle and have the drawing give me the blade tilt angle and the face angle so I can cut these with a sliding compound miter saw or table saw.
It sounds simple enough but I can't get it to work right, it's driving me nuts
Could someone please help me with this, I'd be so grateful. I have a program I bought a while back from the web for crown molding but it doesn't work on something like this.
example: Looking down in Plan view the wall angle is 75 degree's. The one panel is on a 10 degree slope, and it dies into a panel that is completely vertical with no slope. I've got several of these all varying in wall angles.

Also if anyone knows of a simpler approach I'm all ears.
