When reviewing a delivered model, it's been hard to tell at a glance which parts of the building were measured closely and which areas need closer attention. The new point cloud LOA overlay makes accuracy visible directly inside the BIM viewer — no separate software needed.
What's new
A Verify button now appears in the viewer toolbar for models that have been reviewed and cleared by IPX's QA team ("Verified by IPX" versions). Clicking it overlays the original scan data on top of the Revit model, colorized by how closely the model matches the point cloud:
This gives you an immediate, spatially grounded read on model accuracy across the full floor plate — useful when handing a model to a design team, verifying coverage before starting renovation work, or building a case for sign-off.
How to find it
Open any location in the BIM tab. If a "Verified by IPX" model is available, the viewer selects it automatically. The Verify button appears in the toolbar at the top of the viewer. Click it to load the overlay. Click the (i) icon next to the button to read an explanation of the LOA methodology — what the 50 mm threshold means and how the distances were computed.
To see the original scan colors instead, toggle RGB in the toolbar. The point cloud stays visible; only the colorization changes.
A few things to know
The Verify button is scoped to verified model versions only. If you switch to a BIMIT Engine version (earlier or automated drafts), the button is hidden — those versions have not passed the 37-point human QA/QC and do not carry a signed-off accuracy dataset.
Section planes work with the overlay active: cutting the model also cuts the point cloud at the same plane, so you can slice through walls and review accuracy at any elevation. Switching to Elements mode clears the overlay colors and restores original Revit material appearance; clicking Verify again reapplies the overlay.
Locations without a verified model on file will not show the Verify button. Coverage will expand as more verified deliveries are issued.
