Use this procedure to attach, detach, or sort calculation modifiers for spaces.
Calculation modifiers are values and formulas that can be applied to the area and perimeter values of a space to modify them. By default, a calculation modifier is applied only to the base area and base perimeter of a space. To apply the modifier to the net, usable, and gross boundaries of a space, you need to create and apply a property set definition that includes properties for these boundaries.
- Select the spaces you want to attach a calculation modifier to, and double-click one of them. Note: This procedure can be applied to multiple spaces only when they all have the same modifiers attached in exactly the same order.
- On the Properties palette, expand Basic, and expand General.
- Click the setting for Calculation modifiers.
