# Roof Elements - Recalculate Elementing

The "Recompute Elementation" function regenerates the components of the elements. This is useful when element boundaries have been changed (moved, deleted, added) or when the settings of one or more elements have been modified. If the program were to perform an automatic recomputation continuously—for example, merely because one is adjusting the settings of several elements—this would cause disruptive interruptions. Therefore, such changes do not trigger an automatic recomputation; instead, you initiate the recomputation yourself once you have finished making changes.
