STEM provides direct access to the Unset and Freeze commands for whole model elements. From either the main Edit menu, or the Edit sub-menu on an icon menu:
- Select Freeze to remove a formula for the whole element, setting all the inner fields to the values previously imposed by that formula, while preserving any nested formulae for individual inner fields.
- Select Deep Freeze to remove all formulae for and within the element, setting all the inner fields to the values previously imposed by those formulae.
- Select Unset to remove a formula for the whole element, restoring system default values only to those inner fields which were previously unset, while preserving any values overriding the original formula.
- Select Unset Below to restore system defaults to the entire element.
