How do I change the units from millimeters to inches? I tried using the settings, but even if you change it there, it doesn't work on the display.
As far as I know, you can't make the grid that appears on the home screen display inches instead of millimeters. However, RDWorks does have a help file which you could search for additional information. Furthermore, there's a forum created specifically for RDWorks users and I recommend posting your question there and you will probably get the answer you need.
