To Specify the Application for a Calculation Modifier Style

A space contains 2 values that can be affected by a calculation modifier: the area and the perimeter. You can choose to have a calculation modifier apply to either or both of these calculations.

For example you might want to set up a modifier that reduces the calculated base area by 50 percent. (This is obligatory for several space types in various international architectural standards.)

Or you might want a modifier that deducts length from the perimeter of a room for openings and stairs. This would be helpful in calculating the amount of baseboard material needed for this room.

1. Click Manage tabStyle & Display panelStyle Manager.
2. Expand Documentation Objects, and expand Calculation Modifier Styles.
3. Select the modifier for which you want to set the calculation type.
4. Click the Apply To tab.
5. Select whether you want to apply the modifier to the (base) area or (base) perimeter of the space. You can also select both values here.
6. Click OK.
