I want to cut a lid for a box that it 6x6 inches.
I want to use a 6x6 piece of wood
Cut a rabbit around the out side that is 3/8" wide.
Do I just create another square that is 3/4" smaller and center it
Then cut a pocket between the inner and outer lines.
I have done this and when I show preview it shows that the cutter (25EM) did not cut off the corners edges because of it being round.
So what else can be done to clean out the whole area.

Toolpaths are created from the center of the bit so if you want to clear a whole area without rounded corners you have to increase the vector size by the radius of the bit.

Thanks Jeff

You need to increase the vector size by the radius of the bit only on two opposite sides. for a 6" x 6" box the outside vector needs to be 6" x 6 1/4". Actually, in practice I would make that 6 1/8 x 6 1/4 to be sure I cut all of the edge.

A minor correction, but the principle could save time on a larger project.

Edit: If you are adding to all of the sides, the theoretical addition on each side needs to be only cutter radius/sqrt 2 = .125/1.414=.0884. But now I am picking at nits.

OK this is what I came up with .The 6x6 piece of wood is the finish size I want to have.
I need it to have a.375 Rabbit all the way around the edge. So I created a 5.25" square and centered it on the 6x6 board.
Then selected it and set profile cut to the outside, Set my depth of cut and selected a .5" end mill.
Ran the simulation and all the wood was cut out showing a .375 rabbit all the way around.
