Revit Shared Parameters

Managing Shared Parameters for Revit models to support quantity takeoff and cost estimation.

Parameters Overview
Overview of parameter assignment in Revit
Recommended Practices
  • Shared Parameters are parameters that rely on an external .txt file as a central repository for non-default parameters. Make sure the file path is set correctly.
  • For cost estimation, Shared Parameters are mainly used to assign price-related data to model elements
  • The RSB_PROFESSIONAL Template already embeds Shared Parameters for all frequently used Families, ready for price referencing
  • For new Family types outside the template, assign a Keynote matching the desired work category so the Add-in can look up pricing
Example Data Assignment (see image on the left)

RSB_LossPercentage : (Field-loss percentage)


RSB_LabourUnitCost : (Labour unit cost)


RSB_MaterialUnitCost : (Material unit cost)


RSB_ProductImage : (Embed an image to the model element)


RSB_Updated : (Progress tracking)
