Geomagic 2D drawings are defaulting to Metric units when using not using a drawing template. I use standard landscape mode for exporting my parts into my CAM program. This used to work fine but I must have changed something somewhere by mistake.

The Part properties are set up for inches when designed, but the drawing is always in mm.
I have to go set the primary units each time in the Drawing Properties, but for Dimensions, the "use as default" check box is grayed out.

Anyone know how to get my defaults back?
