AutoCAD Map 3D

[#1]

I get an error message when I load a map with Map 2009 (XP) that was last saved by 2012 (Win7 x64).  The error message is this:

Warning: Drawing {drawing name} was created with a version of coordinate system {coordinate system name} that is different from the version installed on your system.  Coordinate conversion operations may generate incorrect results.

I tried opening and saving it with 2009 but the error persists.  What causes this error and what can be done about it?

Hi,

>> What causes this error and what can be done about it?

That with Map3D2012 there are a lot more coord-systems available then in 2009. And when you now open the drawing with an older Map3D version you either have not defined this coord-system or with other definition-details.

If you can verify that your 2009-version has a projection-system defined equal to that of 2012 then you should be able to assign it using the command _ADESETCRDSYS.

If you have not the same coord-system in your 2009-version you will be unable to mix data of different systems with your Map3D and this drawing.
