Delete geometry but keep record

When you delete a geometry (industry model) Map also deletes the database record as well. In some situations you just want to delete the geometry of a feature but keep the record. How do you do this?

in Administrator:
(1) add the Geometry/Coordinate Editor control to the form

Administrator - Form Designer - add control....

in Map:
(2) set form in Edit mode
(3) open Geometry editor (button will appear next to the Editor control)

... Map - Form - use control to delete geometry.

(4) In the Geometry Editor window you can delete - step by step - all vertices of a feature (you cannot delete the whole feature in one go). After deleting all vertices don't forget to "Update" the record to make the changes permanent.
