First day of use. Can't find in the html manual.
1. I draw a line A -> B -> C -> D -> A and one of the corners is off just a hair. I haven't been able to figure out how to tweek the end point by say 1 grid dot.
2. I'd like to set my resolution to 1/4 or .25 inch with grid points to match - will help solve #1 above. I can't get "sg" any better than 1"
