How To Use One Takeoff and Multiply It by the Number of Units

When a line item with a formula is mapped to a takeoff, the mapping supersedes the formula. To get around this, you can use the multiplier, which will adjust the takeoff quantity, or you can use a formula that is tied to a variable from the Project Tab and map one of the QTO Properties to the variable rather than directly to the quantity.

Using the Multiplier: You can adjust the multiplier and that will update the count. 

Using a Variable tied to a formula: 

Example:

Variable: Room1 = 25

QTO Property Count = 10

Formula: Room1*Count

Changes made to the variable update the Quantity.
