Line length increments
 

I'm feeling lucky as I got a quick answer to an earlier problem I had:

Is there any way to force the line length increments that OG uses when creating lines? I have drawing and want to take away measurements that I can use when cutting up wood. However, measures such as 1 144/568 in. don't do me any good. In other programs I've used in the past, I would be able to insist on increments of a 1/4 in, 1/2 in, etc.
