Deleting Features

Whenever you will have to delete geometry, you will not necessarily have to delete the elements used to create it. The application lets you define what you really want to delete.
This task shows how to delete a sketch on which geometry has been defined and what this operation involves.
Open the Delete1.CATPart document.
1.  Select the rectangle you wish to delete.
2.  Select the Edit -> Delete... commands.
The Delete dialog box is displayed, showing the element to be deleted and two options.
Delete exclusive parents: deletes the geometry on  which the element was created. This geometry can be deleted only if it is exclusively used for the selected element
Children: deletes the geometry based upon the element to be deleted, in other words, dependent elements.

Here, the first option cannot be used because the rectangle has no parents.
3.  Click More.

Additional options and the elements affected by the deletion are displayed. If you can delete the sketch, you can also  replace it with another element.
4.  Click ...PartBody\Sketch.2 to display Sketch.2 from the Replace section.

Sketch.2 appears in the Replace field.
5. 

Select Sketch4, that is the hexagon to replace Sketch 2 .

This operation is now displayed in the dialog box.
6.  Click OK.

The sketch is deleted as well as its children : two pads one of which is filleted. 

A Few Notes About Deletion

Deleting Features Built upon Dress-up Features

If you delete a feature (dress-up or not) previously used to create a dress-up feature, the dress-up feature is recomputed.

In this example, thickness was added to the pad, then material was removed from the whole part using the shell capability. In other words, the existence of the shell depends upon the existence of the thickness.

You will notice that only the thickness has been deleted. CATIA keeps the shell feature.
Keep in mind you can apply the Undo command if you inadvertently deleted a feature.
 
You are not allowed to delete a profile used to define a feature, unless you delete the profile to construct another one.
 
Patterns

Concerning patterns, applying the Delete command on one instance deletes the whole pattern.
