Parameter Groups and Filling Rules

4.2. Parameters

Revit Built-In

Revit Built-In is a system-defined group of parameters and properties that are built into the Revit software by default.

These parameters are predefined at the platform level and cannot be deleted or renamed by the user.

• Name – Defines the unique name of the parameter as it appears in the user interface and is used within the model.

• Revit Built-In Parameter EnumName – This is the internal system name (identifier) of the built-in Revit parameter. It is represented as an enumeration value, which is used within the Revit API to reference a specific built-in parameter.

• Revit Built-In Parameter EnumValue – This is the integer value corresponding to a specific built-in Revit parameter within the BuiltInParameter enumeration. It is used in programmatic code as the numeric identifier of the parameter.

• Revit Built-In Parameter Name – This is the display name of the built-in parameter in the Revit user interface. It is the name visible to users when working with model elements, in object properties, schedules, and filters.

• Notes – A parameter intended for storing additional textual information, explanations, or comments related to this parameter.

Revit Shared

Revit Shared is a group of parameters related to Shared Parameters in Revit.

• Name – Defines the unique name of the parameter as it appears in the user interface and is used in the model.

• Disciplines – Specifies the domain or discipline to which the parameter belongs.

• Revit Data Type Discipline – The discipline of the parameter as recognized in the Revit environment.

• Revit Data Type – Defines the data type that determines the format and behavior of the parameter’s value in Revit. It specifies what kind of values can be entered and how they are interpreted, displayed, and processed in models and schedules (e.g., Text, Integer, Length, etc.).

• Shared Parameter Category Id – A unique identifier for the Revit element category to which the shared parameter can be assigned. It determines which object categories in the model will support this parameter when it is added.

• Revit Shared GUID – A user-generated unique identifier for the parameter, intended for use in a Shared Parameters file.

• Notes – A field for storing additional textual information, explanations, or comments related to the parameter.

• Revit Group in Properties – The group in the Revit Properties panel under which the parameter will be displayed.

• Phase – Specifies the project phase in which the parameter is expected to be filled out in Revit.

• Example – A sample value demonstrating how the parameter should be completed.

• Shared Parameter Group – The group to which the shared parameter belongs.
