In cutting 2d I notice that sometimes when I highlight a contour that I have constructed I am unable to enter a value into the inset option box + or -. On some of the other options I created it works just fine.
What is wrong with the contours that I can't enter the values. Also on doing a carve region can I chose carve region and just give a .375 tool dia. or is just limited to a .187 tool. Any help will be of value
