Hi Andrew,
I couldn’t tell you all the problems we have been having, mainly because there is a higher up in our office who is very well-versed in CAD and he seems to be the one running into problems periodically. He knows much more than myself, so he is usually the one who troubleshoots these issues then feeds me the info.
I do know that one of our most recent issues has to do with XY Coordinate points [I think that is what you mean by survey points??]. We had to insert these blocks into the sheet files because for some reason they would print 0,0 even though in the print preview the full coordinates would be showing up. I read on a forum that it is a common problem. Other issues, annotative scaling, LandFx compatibility, X-Ref attach, creating NE blocks.
Here is a forum that lists the commands and variables not included in AutoCAD LT version: http://www.cadforum.cz/cadforum_en/qaID.asp?tip=6397.
