I'm working in Autocad 2015 full and when I try this it all works fime, when my colleage woking with Autocad light tries to insert a reference file in the topographical drawing he somehow manages to get unnamed usc settings which screw up the basepoint of the drawing. When UCS set to world it works fine again.
I tried to recreate this situation but can't figure out what happened which makes the UCS change to unnamed with (seems like) random values for x and y
Does anyone have any idea what causes this???
