Changing Coordinate Systems
Concept Procedure
 
 
 

To change the coordinate system assigned to the data you are adding to a map

  1. In Display Manager, click DataConnect To Data.
  2. In the Data Connect window, select the appropriate data provider in the Data Connections By Provider list.
  3. Navigate to the data store and select it.
  4. Click Connect.
  5. Hold your cursor over the name of the data store to see a pop-up window that displays its coordinate system, for example, UTM27-10.

    When you add data to your map, you must specify its original coordinate system. AutoCAD Map 3D automatically converts the data from that coordinate system to the one specified for your map.

  6. Click Edit Coordinate Systems and, in the Edit Spatial Contexts dialog box, click the entry.

    Select the entry and click Edit to specify the coordinate system for the surface

    NoteTo copy the spatial context information to the clipboard (for example, to check against your records or for use with a Technical Support specialist), right-click the entry and click Copy Coordinate System.
  7. Click Edit.
  8. In the Select Coordinate System dialog box, select the coordinate system you saw in the pop-up window.

    Select the appropriate category from the pulldown list, and then scroll through the entries until you find the one you want.

  9. Click OK twice to return to the Data Connect window.
