Upload model version

Upload two files and clash them in one step →

A new upload into an existing project becomes the next version and is compared with the previous one after its clash test.

New clash: model A vs model B

    The files include every change applied to this model (saved fixes and changes applied but not saved yet).

    Only Revit itself can write .rvt files, so the RVT option is a script that updates your real model inside Revit.

    Claude for clash fixing

    With an Anthropic API key, Claude (claude-opus-5-5) reviews the geometry-checked candidate moves, picks one or sends the clash to a modeler, and explains why. The key is stored only on this computer (in the app's data folder). Without a key the rule-based solver is used.

    Merge models (model vs model clash)

    Each model keeps its own Navisworks Element IDs. After combining, run a clash test with “model vs model only” to clash e.g. SM against Elec.
