9.6 LCC Revit Plugin

What the Plugin Does, and What It Needs

The LCC Revit plugin brings an LCC model into Revit and turns the scan into native Revit geometry through real-time synchronization and AI-assisted modeling. It adds an LCC module to the Revit Add-ins tab, shows the scan in an embedded viewer, and builds levels, walls, doors, and windows from what the scan captured. It is the bridge from a 3DGS scan to a BIM deliverable without leaving Revit.

Import the Model and Work in the Viewer

1. Open the wizard. In Revit's top menu, click the LCC Model tab, then Wizard. The LCC Project Wizard opens in the right panel.
2. Load the model. Click the plus button, select the .lcc file, and load it. The wizard shows the file path, point count, and the unit, which matches your Revit project.
3. Work in the LCC Viewer. The viewer opens automatically and shows Connected in green when it is linked to Revit. Click Sync to push changes between the two: edit in Revit and Sync, or adjust in the viewer and Sync. Use View Switching to toggle between the 3DGS view and the point cloud, and Filter to show or hide layers in either model.

Generate Levels, Walls, Doors, and Windows

The plugin builds Revit elements three ways: Draw them by picking points in the viewer, adjust them in Canvas across multiple views, or auto-generate them with One-Click Modeling. One-Click uses Spatial Recognition data; Draw and Canvas do not. Build levels first, because walls are placed between a Bottom and a Top level.

Levels

1. Open the tool. In Revit's 3D view, click Modeling Tools, then Level. The Create Level window opens.
2. Add a level name, for example Top, then go to the LCC Viewer, navigate to the ceiling, click Draw, and click the ceiling. The point turns green.
3. Return to Revit and click Finish. The point turns red and the level is created. Repeat for a Bottom level drawn on the floor.
4. Or auto-generate. With Spatial Recognition data, One-Click Modeling places the levels at the identified floors and ceilings in one step.

Walls

1. Open the tool. Click Modeling Tools, then Wall. The Create Wall window opens.
2. Set the parameters. Select the Bottom and Top levels, then choose a wall type from the dropdown. The wall type carries the thickness.
3. Draw the wall. In the LCC Viewer, click Draw, then click turning points along the wall path. The points turn green. Return to Revit and click Finish to create the wall.
4. Or auto-generate. One-Click Modeling creates the walls from Spatial Recognition data. Review and fix any that are misplaced before moving to doors and windows.

Doors and windows

Doors and windows use the same pattern. Click Modeling Tools, then Door or Window. Choose the type from the dropdown, which sets the size. Click Draw in the viewer and click the bottom-center point of the opening; the element aligns to the wall automatically. Return to Revit and click Finish. One-Click Modeling places all doors or all windows from Spatial Recognition data at once.

Canvas: Fine-Tune Against the Point Cloud

Canvas adjusts elements you have created, viewed against the point cloud from multiple angles. Open it from Revit when Revit is not in edit mode. It is where you correct the AI's output and match geometry to the real structure.

Exit Editing is the step that saves a Canvas change. Use it before you leave a segment or element rather than clicking away.

LCC Overlay: Check As-Built Accuracy

LCC Overlay displays the LCC point cloud on top of the Revit BIM model, so you can compare the model against the as-built condition and verify accuracy. During overlay the point cloud is view-only; it is locked and cannot be edited in Revit in this version.

To inspect an area, open LCC Overlay, then Point Cloud, and pick a selection method:

Click Clear to remove the selection and restore the original view.
