What it can do

Browses the open model database (sites, children, name search) and reads attributes such as position and orientation in owner coordinates.
Creates elements, boxes, cylinders, tori, extrusions and closed triangular polyhedra, and sets attributes; deletes only when you repeat the exact element path.
Imports a Revit 2026 element mesh as new equipment in a zone, reading it straight from a RevitMCP add-in pipe and checking the placed position.
Leaves every change unsaved until you call save_work with a comment.

Limitations

You must build both projects yourself with the .NET 8 SDK and AVEVA's UE 4.1 customisation environment, then register the CAF add-in in UE.
Talks to a running, licensed Unified Engineering session through a named pipe on the same Windows machine.
No licence file, and the build scripts copy the add-in to a hard-coded D:\MyUE\addins folder.
