Create a custom formula in Organizer
You can create simple mathematical formulas using the object properties that are available in Organizer. You can, for example, calculate areas of specific object types. You can add formulas to property columns in the same way as object properties. You can also use formulas in the object properties when creating property categories.
The formula is shown in the list of properties in the Custom group. You can modify and delete custom formulas by right-clicking the formulas in the list of properties. You can use custom formulas in property templates by dragging the formulas to property columns.
