Details on "Count Room Components"

In this dialog, you map Revit categories and component classes to a target parameter in order to write the respective count of room components to this parameter in the respective room (space). If you want to count components in the rooms of your model, you can use the Revit categories and component classes in this dialog box. The counting is done automatically after mapping.

Target Parameters

List of parameters used to count the room components in the model. After selecting a target parameter via Add New Target Parameter, define the components to be counted in the Filter section using the corresponding Revit categories and component classes. The target parameter must be a Shared Parameter of type integer or number and must be integrated into the project as a Project Parameter in the Spaces category.

Add New Target Parameter

Opens the Select Parameter: dialogSpaces / Number, where you can select a parameter for counting room components from the Shared Parameters that have been included as Project Parameters. The selected parameter is then listed in the Target Parameters section.

Delete Target Parameters

Removes the selected parameter from the list of target parameters. Deleted parameters are removed only from the list, not from the project. They are retained with their values in the space.

Filter

Revit Categories:

Opens the Select Categories dialog, in which you can select Revit categories for the filter.

Component Classes:

Clicking Add Component Class opens the Select Classification: Mep Classes 1.0 dialog, where you can select component classes whose counts are to be accumulated in the selected target parameter. This counts all components that belong to the selected component classes and are present in a room (space).

Room Allocation

Use this drop-down list to select the type of room allocation for the room components.

Room Name/Number on Component

The room allocation based on room name or room number on the component is based on the information specified—i.e., entered—in the Room Allocation for the components. This also allows you to assign components in shafts or suspended ceilings to a room if they have been assigned accordingly using the Room Allocation function. Alternatively, in Revit, you can use component allocation via a Dynamo script or manual assignment to assign components based on room name or number.

Revit-internal Calculation

The Revit-specific allocation is used for room allocation. This assignment is based on room calculation points and component insertion points. For many components, this works well enough (e.g., air diffusers with a room calculation point or plumbing fixtures). However, for components located in a suspended ceiling or wall—and thus possibly outside a space—assignment may not be possible. One example would be installing a pre-wall connection set behind a toilet.
