Transforming the Coordinate System of a Drawing
You can transform an existing map from one coordinate system to another
by querying the objects from the attached source drawing into the current
drawing.
The original source drawing is unchanged, but the objects in the current
drawing use the new coordinate system.

To transform the coordinate system of a drawing
1 Open a new drawing.
2 Attach the drawing whose coordinate system you want to transform. See
Attaching Drawings (page 154).
3 In the new drawing, assign the new coordinate system to the current
drawing. See Assigning a Coordinate System to the Current Drawing (page
147).
4 If you have not already assigned a coordinate system to the original
drawing, do that now. Assign the coordinate system that was used to
create the original drawing. See
Assigning a Coordinate System to a Source
Drawing
(page 146).
5 Define a query to bring in all objects from the source drawing. The easiest
way to do this is to define a location condition and use the Boundary
Type "All." This retrieves all objects in the source drawing. See
Finding
All Objects in a Specified Location
(page 1241).
As the objects are retrieved from the source drawing into the current drawing,
they are transformed from the coordinate system of the source drawing to the
coordinate system of the current drawing.
Once the objects are in the new drawing, you can detach the source drawing
and save the new drawing. The objects are unchanged in the source drawing,
but they use the new coordinate system in the new drawing.
