The Cost tab from the action center at the bottom of the application accesses the concept estimated cost. As soon as new design elements are added to the concept, the refresh tool needs to be pressed in order to get the up-to-date estimation. The total cost of a concept is based on different parameters. Some of them are configurable in the Quantities and Cost Report Configuration panel (accessible from the backstage).

Refresh

The refresh tool launches the calculation of the concept cost estimation. It is required to use this refresh tool as soon as new items are added to the concept.

Press and hold refresh will recompute all items that contain a quantity and cost.
