Local Revit model diffing vs cloud BIM 360 compare.
How on-premise SQLite diffing inside Autodesk Revit eliminates cloud upload delays, model size restrictions, and security risks when tracking linked consultant revisions.
Direct Technical Comparison
| Capability | Karo.WhatsChanged (Local) | Autodesk BIM 360 / ACC (Cloud) |
|---|---|---|
Model Processing Location Karo never transmits model geometry, coordinates, or parameters over the internet. | 100% On-Premise (Workstation RAM) | Public Cloud (Autodesk Forge / ACC) |
Processing & Diff Latency WhatsChanged computes deltas immediately upon link reload in Revit. | 2–5 Seconds (Local SQLite Engine) | 10–25 Minutes (Cloud Processing Queue) |
Model Size & Element Limits Handles campus masterplans and complex multi-gigabyte models without crashing. | Unlimited (Any file size workstation can open) | Constrained by browser WebGL & cloud memory |
Direct Revit Session Interaction Isolates and edits modified elements directly in your active Revit session. | Native (Focus Dim & Auto 3D Section Box in RVT) | External Browser Viewer Only |
Air-Gapped & Strict NDA Compliance Approved for defense, government, and healthcare confidential BIM environments. | Fully Compliant (Zero internet required) | Requires continuous internet & cloud access |
Subcontractor Coordination Reports Generates clean change matrices ready for weekly consultant coordination meetings. | Instant formatted Excel & PDF Workbooks | Web screenshots or basic CSV export |
Zero Cloud Exposure & NDA Safety
Confidential healthcare facilities, defense contractors, and high-security government projects strictly forbid uploading building geometry to external multi-tenant cloud platforms. Karo.WhatsChanged runs entirely in local RAM and writes encrypted SQLite diff caches to local disk.
In-Session Focus Dim & Auto Section Box
Cloud viewers force BIM coordinators out of Revit into a separate browser tab. With Karo.WhatsChanged, clicking a changed element in the report automatically zooms, dims unchanged geometry in the active view, and generates a tight 3D section box directly inside your Revit model.
