Combine Data with Different Coordinate Systems

AutoCAD Map 3D Workflow

 
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 each drawing directly, without attaching it to a map

   

Specify the coordinate system for each drawing

   

The drawings are saved with the assigned coordinate systems

   

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

   

All data you add to this map is transformed to this coordinate system

   

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

   

Use a query to bring in objects from the attached drawings

   

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