We need the Model Compare tool to have the same dedicated workspace capabilities and persistence as Model Coordination (Clash Detection). Currently, comparing versions in ACC/Forma is primarily an ephemeral review tool. We need a persistent environment to track, document, and present design deltas (additions, deletions, and modifications). Key Capabilities Requested: Saved Comparison Views: Ability to create, name, and save filtered comparison views (similar to saved clash views/coordination views) to return to specific delta analyses across versions without re-configuring filters every time. Direct Issue Creation: Ability to pin an ACC Issue directly onto a changed, added, or removed element inside the comparison environment, automatically tagging the version delta metadata. 3D Markups: Support for persistent 3D callouts, measurements, and markups highlighting changes directly on the compared geometry. Presentation-Ready 3D Exports: Export high-resolution snapshots, 3D views, or formatted change reports (PDF/images) showing the color-coded deltas (Added, Removed, Modified) for stakeholder, client, and executive review meetings. Multi-Model / Cross-Trade Comparison: Ability to compare combined multidisciplinary models side-by-side or overlaid, just like running clash matrices in Model Coordination. Business Value & Use Case Managing design creep and scope changes is just as critical as managing spatial clashes. Today, documenting what changed between model iterations requires manual screenshots and external slide decks. Bringing the structured workflow of clash coordination (views, issues, tracking) into model comparison will dramatically accelerate design review meetings, scope change approvals, and client presentations.
