To clean up objects in a map

  1. Open the drawing containing the objects to clean or query the objects into the current drawing.
  2. Because your map may be altered during the cleanup operation, back up your data before starting.
  3. Click Tools tabMap Edit panelClean Up. At the Command prompt, enter mapclean.
  4. Follow these steps:
  5. Click Finish.

    AutoCAD Map 3D performs the cleanup with the options and values you specified.

  6. Depending on whether you selected Interactive or Automatic, AutoCAD Map 3D does one of the following:
    • If you selected Interactive mode, AutoCAD Map 3D displays a list of detected errors. You can review the errors and decide how to handle them. For example, you can place markers on the errors, correct them, or ignore them.
    • If you selected Automatic mode, AutoCAD Map 3D corrects all detected errors automatically and reports a summary of the results on the command line.

You can run the operation again to verify that you corrected all existing errors. Cleaning up geometry in a drawing creates new geometry and new relationships between the objects. You may need to repeat the cleanup operation.
