Independent Material Takeoff sheet

[yafimski]

Hi,

I know that I can create a new sheet and place a material takeoff on it like so:

// Create material takeoff
ViewSchedule materialTakeoff = AssemblyViewUtils.CreateMaterialTakeoff(_doc, _assemblyInstance.Id );
ScheduleSheetInstance.Create(_doc, viewSheet.Id, materialTakeoff.Id, new XYZ(2.25, 1.5, 0));

but, what if I want to duplicate the capability of Revit to create a Material Takeoff independently? If you right-click on Schedules\Quantities (all) in Revit, you can create a "New Material Takeoff" which will not be placed on any sheet, and will be create independently.

I can do the following:

ViewSchedule materialTakeoff = AssemblyViewUtils.CreateSingleCategorySchedule(doc,
assemblyInstance.Id, categoryId);

but this doesn't translate into anything real in Revit (after ending the Transaction).

So is there a way to create the takeoff without placing it on an existing sheet?

Thanks

If your takeoff isn't specific to assemblies???

ViewSchedule.CreateMaterialTakeoff(Document, Category)

Category = InvalidElementID for multi category.

I prefer to filter elements by Category.HasMaterialQuantities

and use Element.GetMaterialVolume(Material as ElementID)

Then you find Categories such as stairs don't have material quantities.
