I have found with Carlson Survey XML that if I try and align a drawing with
points and linework from say an assumed coord system,(N5000 E5000) to a
State Plane Grid system (N500,000 E1,500,000) the points and lines go
haywire to some small degree. If I simply move the drawing close to the new
coords then align everything seems to go OK. Does this make any sense?
