Base quantities are quantity definitions that are independent of a particular method of measurement and therefore internationally applicable. Base quantities are defined as gross and net values and provided by measurement of the correct geometric shape representation of the element. Additional Quantity takeoff add-on view is included to the exported IFC model if you set Base quantities to Yes in the Tekla Structures IFC Export dialog box.
The Quantity takeoff add-on view contains the following base quantity information on the entities in the exported IFC model:
