Model Upgrader Pro is a high-performance batch processing add-in for Revit designed to streamline annual version migrations for BIM Managers, Project Leads, and Architectural/Engineering teams.

Upgrading complex project directories to newer Revit versions used to mean opening each file manually, handling endless popups, waiting for views to regenerate, and dealing with broken link dependencies. Model Upgrader Pro automates the entire migration pipeline in memory without populating view tabs or disrupting active Revit sessions.

Key Features:

• Batch Upgrade Models & Families: Upgrade multiple .rvt project files libraries in a single pass.
• Deep Directory & Subfolder Scanning: Recursively scan target folders with instant file count and version detection notifications.
• Transmission Data Link Inspection: Automatically inspect nested Transmission Data links inside parent models to identify and queue linked models before upgrading.
• Background Processing: Processes models directly in memory without drawing visual view canvases or cluttering the active Revit document session.
• Worksharing Central Path Re-establishment: Option to automatically re-centralize workshared models upon upgrade completion.
• Audit File on Open: Force Revit's internal audit engine during open to resolve geometry warnings, corrupt elements, and schema issues.
• Detach & Backup Cleanup: Detach worksets cleanly and automatically purge redundant *_backup directories post-upgrade to save disk space.
• Duplicate Sublink Protection: Smart deduplication prevents processing identical linked models twice across parent projects.

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