After creating a Takeoff, you can add it to the Library. This creates a template so you can use the Takeoff over and over again for future projects. Start by clicking the 3 dots next to the takeoff name to access the sub-menu. Then click "Library"
On future projects, click the Library tab to access all the stored templates.
To draw, simply click the arrow next to the takeoff name.
TIP: If there are items or assemblies attached to the takeoff, they will still be attached when starting the takeoff from the library.
