I am basically making a shoe box cover
but have many to do, all different sizes.

I need to make a rectangle the required size. I then need to cut 1" in with a v bit to make the fold. The problem for me is I need the inside box 1" smaller but the lines must go to the end of the panels.
The customer cuts the corners off with hand tools.
I have been using create poly line. Takes a long time to make cut files for 50 parts.
Any body know how I can do this quicker.
TIA
Dave
