Join Retriever

easy BIM rule-checking


One-click check


Join Retriever is embedded in Revit. With a single click, you can painlessly check a library of rules, ensuring health and compliance of your Revit models.

Retriever ships with dozens of commonly-used rules collected from architects and BIM managers. Rules range from safety compliance on fire rating to energy compliance on window-to-wall ratios, and from good naming conventions to simple in-Revit clash detection.
