OverSite Pro overlays your BIM models (GLB) inside a Matterport scan, so the real scan occludes the model — services behind a wall stay hidden until you reveal them. Load models from your computer or straight from Autodesk (Forma/ACC), align them to the space, and save the setup so anyone can re-open it with one click.
Paste a Matterport space URL or ID into the box at the top and press Load. Use × to clear it. The model only loads public or unlisted spaces unless OAuth has been enabled on the Matterport key.
Click Load GLB… and pick a .glb file. Each model gets its own row with an
opacity slider and a × to remove it. Click a row to select it — the align tools
act on the selected model.
Export from Revit to IFC4, then drop the IFC onto the IFC Optimiser to get a small, correctly-georeferenced GLB (metres, Y-up, shared coordinates).
Load models straight from Autodesk Construction Cloud — no download needed.
Then browse Hub → Project → Folder and click a .glb to load it (or a
.json to apply a saved alignment). Use Sign out to switch account.
Select a model in the list first. The alignment tools are grouped under Alignment — use its Hide / Show toggle to tidy the panel.
| Tool | What it does |
|---|---|
| Centre model | Brings a far-away model (it loads at its survey coordinates, kilometres off) to the centre of the scanned space — your starting point. |
| Rotate | Spins the model's heading by the chosen step (90/45/15/5/1°), pivoting on its centre. Use 90° to flip, then 5° to fine-tune. |
| Move X / Y / Z | Nudges the model by the Step distance. Z is up/down (BIM convention); X and Y are the two horizontals. |
| Gizmo | Tick it, then drag the on-screen handles to move the model directly. |
| Units | Scale preset for the model (metres / mm / feet). |
| Apply selected to all | Copies the selected model's placement to every other loaded model — handy for federated disciplines that share one coordinate system. |
Once a space is set up, save it so anyone can reopen it instantly.
One-time setup: in the Forma browser, open the folder you want to use and click ★ Use this folder for space settings. Autoload only covers Forma-loaded models (locally-uploaded files have no shared home).
Export JSON downloads the current alignment of all models. Import JSON applies a saved alignment to the loaded models (matched by filename). Alignment files are space-specific — use the one exported for the space you're viewing.
| Control | What it does |
|---|---|
| Opacity | Global model transparency (each model also has its own slider). Higher = the BIM "pops" and covers the scan; lower = you see more of the scan behind it. |
| Lines | Thin edge lines on the model. |
| X-ray | Draws the BIM on top of everything — always fully visible, even through walls (turns occlusion off for that look). |
| Ghost + Ghost op. | Shows the parts hidden behind the scan, faintly. The Ghost op. slider sets how faint. |
| Quality | Flat colour (fast) vs shaded. |
| Radius | Hides model geometry beyond a distance from you — speeds up navigation in big models. |
Click Hide (top-right of the panel) to collapse the whole interface to a small ☰ OverSite button (top-left) — this frees up the Matterport controls underneath. Click the button to bring the panel back.
