Editing Groups

Click the Features | Group | Start Editing command to manually add new objects to a base layer, an empty base layer, or a grouped object. Alternatively, right-click on a group or base layer and select Start Editing from the context menu.

 

Base layers and groups can be edited. The Start Editing command is enabled when a base (vector) layer or group is selected. Base (raster) layers cannot be edited. If you need to add vector features to a map with a base (raster) layer, add an empty base layer to the map.

 

Edited Group

The edited group is indicated in two ways. First, a message is displayed in the top-left corner of the plot window indicating which group is currently being edited. Second, the sizing handle color changes from a green to a gray. When the group is being edited, the editing commands operate within the group only. New objects can be added to the group. Multiple objects can be selected, deleted, and edited. Queries are performed on the objects in the group.

 

The message indicating the open group is displayed in the top-left corner of the plot window.

 

Stop Editing

The Stop Editing command replaces the Start Editing command while a group is being edited. Click the Features | Group | Stop Editing command to stop editing the group. Exit the group to select or modify objects outside of the group.

 

Editing Groups with Coordinate Systems

When the base layer and map have different coordinate systems, some editing functionality is disabled. This is because a geotransformation is applied to the base layer to display it in the map's target coordinate system. The following processes CANNOT be applied to a geotransformed base layer or objects within the geotransformed base layer:

 

Removing the Geotransformation

If you want to perform one of the processes listed above, you must first change the map target coordinate system to the same coordinate system as the base layer you wish to edit. Alternatively, you can change the map to use an unreferenced local system. To do this:

  1. Click on the Map object in the Contents window.

  2. In the Properties window, click on the Coordinate System tab.

  3. Click the Change button.

  4. In the Assign Coordinate System dialog, note the current coordinate system.

  5. Click the next to Local System.

  6. Click the Unreferenced local system and click OK.

  7. Click on the Base map in the Contents window.

  8. Click the Features | Group | Start Editing command.  

  9. Make any necessary adjustments.

  10. Click the Features | Group | Stop Editing command.

  11. Click on the Map object in the Contents window.

  12. In the Properties window, click on the Coordinate System tab.

  13. Click the Change button.

  14. In the Assign Coordinate System dialog, define the coordinate system as it was assigned in step 4 and click OK.
