I feel pretty stupid for asking this, I suspect this'll lead to one of those "DOH!!-slap head" moments.
Anyway, I have a Map3D 2006 dwg that refuses to return accurate (getpoint) coords. It does it's thing as usual but rounds the returned coords up or down to the nearest unit. It appears to be 'dwg' specific so Im guessing it's a system variable issue.
I've checked through the usual tweaks such as Dimzin, Lunits, luprec, Unitmode, -dwgunits but no joy.
Am I missing something blindingly obvious?
I forgot to mention, everything seems to work fine in paper space.
