Opening Handing Pro is an automated spatial analysis and parameter management tool for Autodesk® Revit® designed to calculate door and window swing handings accurately according to standard industry architectural conventions (Left Hand, Right Hand, Left Hand Reverse, Right Hand Reverse).

Determining door swing orientation and room transition direction manually across hundreds of doors in a large project is time-consuming and prone to human error. Opening Handing Pro analyzes element geometry, swing vectors, wall orientations, and room bounding boundaries in real time, automatically populating custom or standard shared parameters across all door and window families in your project.

Key Features:

• Automated Swing Direction Calculation: Instantly computes architectural handing codes (LH, RH, LHR, RHR, Inward, Outward) based on opening swing geometry and wall insertion vectors.
• Flexible Parameter Mapping: Map calculated handing codes directly to existing shared parameters, project parameters, or custom instance/type parameters.
• To-From Room Context Detection: Determines exterior/interior side or From Room / To Room transition context for door schedule accuracy.
• Interactive Batch Audit Dashboard: Review and verify calculated handing results in a clean table view prior to updating model parameters.
• Flipped Opening Identification: Detects doors or windows that have been mirrored or flipped across axes to prevent hardware and schedule discrepancies.
• Multi-Category Support: Works across Doors, Windows, Curtain Wall Doors, and custom nested opening families.

Note: This app uses a custom installer (and not the standard Design and Make Marketplace installer).
