Highlighted Fields: Layer not available in TO entity or is hidden from users because it identifies the entity (IMPLIED).
* These 2 intersections are mutually exclusive because only one can be enabled at a time.
Note: One generally should put data in the leftmost column possible to reduce repetitious data entry.


Examples of Layered Takeoffs
Entity Examples of Layered Takeoffs
Lot Takeoffs for Lot 25 in Project AB1 for Baseplan 2345
Option Takeoffs for Option B in Baseplan 2345

Takeoffs for Option A used anywhere
Baseplan Takeoffs for Baseplan 2345M in Project WV13

Takeoffs for Baseplan 8976 used anywhere
Division Lot Takeoffs for all lots

Takeoffs for all lots in Project WV13
Division Baseplan Takeoffs for all baseplans

Takeoffs for all baseplans in Project AB1

Takeoffs for all baseplans used in Baseplan Construction Type Single
Note: Each point represents a Junction in the Entity.

The advantage of using this approach is when you update takeoffs; you only have to update one Junction to propagate the changes through the system. Whereas in D3, you have to update the layers for each takeoff affected by the change wherever it is used.
