I'm wondering if it's possible to affect how UCS
icon is displayed and if there are ways to customize it beyond it's
original purpose. I'd like to make a dynamical scale bar as seen on topo maps,
to graphically reflect current drawing scale (just like ACAD tray "Scale factor"
does, it's right to the Paper/Model button). Scale bar is more like a
visual aid, since it's not precise as present "Scale factor" but gives user a
better insight into distances between objects.
It seems to me that UCS icon is being
drawn using GRVECS (?), since it refreshes itself as user performs pan/zoom.
This should be a starting point for the tool's logics. Please correct me if I'm
