The Revit Parameter field type allows you to connect Revit model data directly to a field in Layer. This field enables you to display parameter values from synced Revit elements and optionally write updates back to the Revit model using Layer Automations and the Revit Add-In.

While most data in Layer exists independently from a Revit model, Revit Parameter fields are directly tied to the underlying model geometry and data. Revit Parameter fields can be used in read-only mode to view model data or in write mode via automations to push field values back to Revit.

Field Behavior

Revit Parameter fields behave differently from standard field types in Layer:

• Read-only by default

• Field value availability depends on model sync

• Only visible on Revit-linked Elements

• Field value updates do not push back automatically
