Dataflow Add Basic Quantities

The Add Basic Quantities dataflow calculates geometry-based dimensions and quantities for selected objects and assigns the results to standard properties within a Simplebim property set. The selection of calculated quantities for each object depends on its object class (see below), while the property set and property names remain consistent across all object classes.

This dataflow provides an easy way to add standardized quantity data for all objects. These quantities enable combining different object classes within the same quantity take-off or calculation process.

Settings

Step Name

The name of the dataflow step. The step name can be edited manually.

Target Objects

The objects the quantity properties will be added to. If the target is an object selection or object group, the new properties will be added to all object classes for which the target has objects. However, the Value (see below) will be set only for the objects in the target. The default value for the target is All.

Automatically added properties and values

Image: Calculated counts and dimension quantities for all object classes (all elements, including both assemblies and parts).

Image: Calculated area and perimeter quantities for Beam, Building Element Part, Column, Covering, Door, Slab, Wall, Window, Element Assembly, Roof, Curtain Wall, Ramp, and Footing. For Space: 05_Area shadow net, 05_Perimeter, and 05_Perimeter inner.

Image: Calculated volumes for Beam, Column, Covering, Slab, Wall, Element Assembly, Roof, Ramp, Stair, Footing and Space.

Image: Calculated frame lengths for Door and Window objects. For Windows, the frame length is calculated as the perimeter; for Doors, it is calculated as (2 × height) + width.

Image: Additional interpreted quantities derived for selected object classes, including Walls, Slabs, and Spaces. These quantities provide more intuitive and practical values for analysis and reporting.
