There are several options which you can set in Takeoff that control how takeoff is carried out. These include Unit of Measurement, Insulation, Pressure, Dimensions, Takeoff Menu, Size, Formula, and more.
There are three ways to access the Takeoff options:
From the Open Section window upon entering Takeoff,
Directly in the Takeoff window, with Options displayed, or
By selecting File > Options > Takeoff Options in the Takeoff window.
MANAGE LEVELS BY: This menu allows you to choose how your levels are displayed in the window below.
Note: The drop-down list under Manage Options By can be used to select a Level Type to use when managing options (instead of a Section). If no options are defaulted for the Level Type, the options for the active section will be used. When making changes to Level Type options, your changes will only apply to sections that have not yet been entered in Takeoff. If Section options are not defined and have not been entered, the Job/Estimate defaults are used when entering Takeoff.
RETAIN ACTIVE LEVELS BETWEEN SECTIONS: This option, when checked, will cause your active Levels to remain active when switching to another Section.
Use the following links for information on each tab:
Takeoff Options tab: Dimensions
