Deleting entities

You can remove entities from a drawing. You can delete entities using any of the entity-selection methods.    

To delete a selection set    

   1   Do one of the following to choose Delete ():

    On the ribbon, choose Home > Delete (in Modify) or choose Edit > Delete (in Modify).

    On the menu, choose Edit > Delete.

    On the Standard toolbar, click the Delete tool.

    Type delete and then press Enter.

    2    Select the entities, and then press Enter.

Typing the Undelete command restores the most recently deleted selection set.
If you have made additional modifications since deleting the entities, use Undelete rather than Undo to restore those entities without reversing those modifications.    

The Overkill command deletes extra entities all at once.
If a drawing has overlapping or duplicate entities that you want to delete or combine, for example polylines with too many vertices, use the Overkill command to clean up the drawing.
