Quick Answer
Scan with SHARE3DCAM → export point cloud as .RCS format → import into Revit as a point cloud link → model walls, floors, and structural elements using the point cloud as reference. Up to 70% faster than traditional measurement plus manual Revit modeling.
Who Should Read This
BIM managers integrating scan data into Revit projects. Architects creating as-built Revit models from existing buildings. MEP engineers needing accurate spatial context. Renovation teams documenting existing conditions.
Stage 1: Capture with SHARE3DCAM
Use a SHARE SLAM S20, S20 SE, or S100 scanner. Walk through all rooms including closets and mechanical spaces. Ensure adequate overlap, capture ceiling and MEP elements, complete loop closure. Output: .LAS point cloud.
Stage 2: Export in Revit-Compatible RCS Format
What point cloud format does Revit support? Revit natively supports .RCS (Autodesk ReCap Scan) and .RCP (ReCap Project). Export from SHARE PointClouds Studio as .LAS or .E57, open in Autodesk ReCap (included with Revit), and save as .RCS. For large datasets, ReCap Pro users can create .RCP projects referencing multiple scans.
Stage 3: Link Point Cloud into Revit
Go to Insert tab → Link Panel → Point Cloud. Select your .RCS file. Choose Auto - Center to Center or Origin to Origin positioning. Verify the point cloud is visible in plan, elevation, and 3D views, position aligns with project base point, and scale is correct.
Stage 4: Model Building Elements
Trace wall centerlines in plan view. Sketch floor boundaries from point cloud edges. Place columns at visible positions. Align beams in section views. Place doors and windows at openings. Set ceiling heights from sections. Model stairs following point cloud geometry. Use wireframe visual style to see Revit elements over the point cloud, and section boxes to isolate areas.
Stage 5: Validate and Complete BIM
Review all elements against the point cloud in 3D view. Add room names, numbers, and material data. Check for missed elements in section views. Coordinate with structural and MEP teams. Remove the point cloud link once verified.
Efficiency Comparison
| Task | Traditional | SHARE3DCAM + Revit |
|---|---|---|
| Site measurement | Hours-days | Minutes |
| Drafting existing conditions | Manual sketching | Point cloud reference |
| Accuracy | Notes + memory | Centimeter-level |
| Site revisits | Frequent | Rare |
FAQ
Can I model directly from the point cloud? No — Revit does not auto-convert point clouds to BIM elements. The point cloud serves as an underlay reference.
What if the point cloud is too large? Clip in SHARE PointClouds Studio or ReCap, use section boxes, split into linked Revit files, or downsample in ReCap.
Does this work for exteriors? Yes — SHARE3DCAM scanners work outdoors for facades, topography, and infrastructure. Combine exterior and interior scans for a complete building envelope.
Summary
SHARE3DCAM scan → Export LAS/E57 → Convert to RCS in ReCap → Link into Revit → Model elements → Validate → Complete BIM. Up to 70% less time on measurement and drafting.
