I have made a couple of boxes, and the incra jig worked perfectly. Now what I would like to do is make a box that will have the lid and bottom already in place before I split the box. I was wondering if there is a program or something, that will add the 1/8 inch to my template so that I can rip the box on the table saw and split it into the bottom and top. in the past, I've added a top and the bottom, and prayed that they lined up. Or I have made a box that had a separate top that wasn't dovetailed or box jointed. Hope this makes sense.
