To Clean Up Drawing Data

Use Drawing Cleanup to correct common geometry errors resulting from surveying, digitizing, and scanning before you define a topology, perform a map analysis, plot a map, or export to a geospatial data format.

   • Converting Objects After Cleanup. Specify how to treat the original objects after the cleanup operation is complete. Click Next.

   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.
