My math skills are non existent beyond basic math, and I'm trying to figure
out how to space holes evenly along a center line in an area. Let's say I
have a rectulanglar block, 6" long ,less 1/4" on each end for a border and I
want to evenly space 6- 3/4" holes. How do you figure that? My
daughter-in-law says you can do that in one of those cheap home design
programs. That would be ideal for me. Anyone use one of those programs that
knows if they can be used for that? Thanks.

Equal divisions on a line using a ruler held at an angle. No
calculation required.
