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 then choose one of the following commands.
- Use Custom Calculation enables 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 enables you to choose some other formula. Example
- Edit Calculation enables you to change a custom calculation.
A ü appears beside your selection.
