What it can do

Creates, runs and deletes Hard, Clearance and Duplicate clash tests and reads their results.
Groups clash results and sets group status (New, Active, Reviewed, Approved, Resolved).
Saves selection sets and property-based search sets and returns their items.
Finds items by property, reads properties, colours and hides items and manages viewpoints.

Limitations

You build the add-in with the .NET 8 SDK and deploy it per Navisworks year.
The add-in serves an HTTP API on localhost:8765 that the Python server calls.
The README's licence section names only the author, so reuse terms are unclear.
