I heard of AUGI forums from a friend and I am very impressed so far! Here goes my first post:

I am using AutoCAD Map 3D 2010 and I have two drawings: 1) survey control points, and 2) a map of the zoo I'm working on. I want to copy the control points drawing into the zoo map drawing so I can see and use all the survey control points layers in the zoo map drawing file (so, basically not an xref). My problem is that when I copy the objects from the survey drawing over, the position and rotation is way off. I checked the coordinate systems of both files before I performed the copy command and found that they are matching.

Is there some sort of "import" function I need to do instead of a straight copy procedure? I've tried a few different ways of copying and I've had a couple different (incorrect) results. Thanks for your help.

What about units? If insertion scale is not set, you may get some scaling problems. Are you using Copy With Basepoint?

I am using copy with basepoint, which I specify as 0,0,0 for the copy and placement. It does not give me an option to scale, but both are using the same scale anyway (foot) so I wouldn't think this is the problem.

I just tried exporting my survey drawing to an SDF file and then imported that into my zoo map. This method works for spatial orientation; however, when I do this, it changes any "annotation" into points and removes all of the text data associated with it (northings, eastings, elevations, and control point numbers)... which isn't very useful.

I've run into this problem before, so if somebody could offer an explanation on this issue I would appreciate it as well, but currently I'm just trying to bring all this information into another drawing.

If the dwg is made up of just drawing objects and/or map objects you can use the drawing attach and query the points and texts in. That's what it was build for.
