Namespace: Autodesk.Revit.DB Class: ViewSchedule

ViewSchedule.CreateMaterialTakeoff

Method

Description:
Creates a material takeoff.

Remarks:
A material takeoff is a schedule that displays information about the materials that make up elements in the model. Unlike regular schedules where each row (before grouping) represents a single element, each row in a material takeoff represents a single <element, material> pair.
