Using the BIM360 Integration
Open Sigma, go to File, New and then click on the BIM360 template to start a new estimate.
In the next window that opens, there are 2 radio buttons: You may use the default settings, or, if you use a cost library, the units will be applied that are associated with the cost items from the library. Since a cost library was included with the model, select “Use Sigma Library for units and quantities.” And click next.
Select Cost data sample in the next window, and rsmeans.csv, and click next.
