About Deleting Geometric Entities
You can clean up your model without affecting other geometry by permanently deleting all the unrequired geometric entities from your model. The deleted entities no longer appear in the graphics window and the Model Tree and are not available for selection.
In Creo Direct you can delete one or more of the following types of entities at a time:
Coordinate system
Datum plane
Datum axis
Datum point
Quilt
Sketch
You can delete the entities either individually or as a combination of one or more of the above entities.
