Changing the calculation methods for assembly items

You can use the commands on the shortcut menu to switch the method of calculating the takeoff quantity of an assembly item. The commands are available from the item grid in the Assembly window.

To change the calculation method (where I - item formula, * - factor, F - selected formula, fy - custom calculation), right-click a cell in the Calculation column and choose one of the following commands. A ü appears beside your selection.

Use Custom Calculation - allows you to set up a special formula for the item. Example
Use Factor - uses the specified multiplier times the assembly quantity. For items without a formula, the default factor is 1.00. If you are creating a new assembly using the Save as Assemblies command, the factor is the takeoff quantity for that item. Example
Use Item Formula - uses the formula attached to the item, if any. Example
Use Selected Formula - allows you to choose some other formula. Example
Edit Calculation - allows you to change a custom calculation.
