I am a right hander. And I’m feeling for the lefties, who face these kinds of problems all the time.
When using a stylus on my Wacom, oriented to the right of my computer, the little window that displays sizes in the lower right corner of SketchUp is obscured by my right wrist. I can’t see dimensions while I draw!
Is there a fix for this, besides learning to stylus-draw with my left hand?
