Deleting Entities

• Use this function to permanently remove one or more selected entities from the graphics window and from the part file.

• You use different methods to delete entities, based on whether you pre-select entities or choose this function before selecting the entities to delete.

• You can pre-select entities using functions in the General Selection ribbon bar. Then, press the Delete key on your keyboard or choose the Delete entity function from the Edit menu.

• An alternate method is to first choose the Delete entity function. Then, select the entities to delete and press the Enter key or choose the End selection button in the General selection ribbon bar.

Undelete

Use these functions to restore one or more deleted entities to the current file. Undelete entity: Restores the last entity you deleted. You can continue to select this option to incrementally undelete entities.Undelete # of entities: Restores the number of specified entities by reversing the sequence in which they were deleted. For example, if you deleted 20 entities and wanted to only delete the first 15, choose this function and type 5 in the field. The last 5 entities that were deleted are "undeleted" and restored to the part file.Undelete entities by mask: Opens the Selection mask dialog box where you can specify the criteria you want to use to select the entities to undelete.

Deleting Duplicates

• Use this function to find and delete duplicate entities in the current file.• You can automatically delete duplicate entities based on their XYZ position and

entity type. If you pre-select entities before choosing this function, Mastercam searches only for duplicates that match the selected entity types. Otherwise, duplicates for all entity types are located and deleted.

• An online summary informs you of the entities that were deleted.
