For example, suppose the Assembly calculation for the Slab on Grade assembly is the Vol CY - Concrete formula and the assembly unit is cy (cubic yards).

Vol CY - Concrete formula:

Slab Length ' * Slab Width ' *( Concrete Depth " /12)/27

Variable values entered during takeoff:

Slab Length ' = 200
Slab Width ' = 100
Concrete Depth " = 6

Sage Estimating plugs the variable values into the formula and calculates the assembly quantity. The assembly unit applies to the resulting quantity:

200 * 100 * (6/12)/27 = 370.37 cy (cubic yards)
