Combine Data with Different Coordinate Systems

Map files and feature sources you use may be created with different coordinate systems. When you bring objects into a map from other sources, AutoCAD Map 3D automatically transforms those objects to the coordinate system of the current drawing.


Open the drawings to combine		Open each drawing directly, without attaching it to a map

Assign coordinate systems to the drawings		Specify the coordinate system for each drawing

Save and close the drawings		The drawings are saved with the assigned coordinate systems

Create a new map file		Create a base drawing, into which you will add objects from other drawings and feature sources

Assign a coordinate system to the new map file		All data you add to this map is transformed to this coordinate system

Connect to your feature sources		Attach the drawings and connect to the geospatial feature sources for the map

Add drawing data to the map		Use a query to bring in objects from the attached drawings

Save the map		The added features and the queried drawing objects use the new coordinate system. The original sources are unchanged.
