kcclarkfw posted a topic in form•Z DiscussionI’m going insane, I know there must be something easy I’m missing. I’ve drawn an extruded rectangle 45’8 by 47’7 by 1’. I want to cut out a part of it to get the outline of my slab. I figured out how to do the cut out, but getting it started 20’5” in from the edge of the rect is eluding me. I can’t seem to figure out how to create a guide 20’5” in from the edge of the box. Any Ideas.
