Exercise 2: Check out and edit a feature

If AutoCAD Map 3D toolset is set to check in your changes automatically, the source file updates while you edit. Automatic update can result in inadvertent changes to the data store. The safest way to edit geospatial data is to turn off automatic update feature before you edit a feature. Once you make your changes, check the feature in to update the data store with your changes and make the feature available to others again.

When you edit a feature, that feature is automatically checked out and locked for editing by anyone else (if the data format supports such locking). Other people can view the feature source, but they cannot change it until you check it back in.

Note: This exercise uses the build_map1.dwg map you created and modified in the previous exercises.

To edit an object

1. If you closed your finished map from the previous lesson, reopen it and display the Data Table for the Parcels layer.
   • Click OpenDrawing.
   • Locate the build_map1.dwg file.
   • Select it, and click Open.
   • In the Display Manager, click the Parcels layer and click Table.
   • Zoom to a parcel on Villa Drive.
     

     The parcel is checked out automatically and displays grips.

2. Make sure the automatic update option is off. (Click Feature Edit tabEdit Set panelAutomatic Update Find.)
