Point Cloud to Model - User Guide & Reference

The Point Cloud to Model utility (Scan-BIM category) Scan-to-BIM wizard. Extracts point cloud datasets, detects walls, floor slabs, ceilings, door/window openings, columns, and stairs from point groups, and creates native Revit elements inside a single transaction group..

1. Overview & Key Capabilities

The Point Cloud to Model tool is designed to improve workflow efficiency by automating standard tasks. Key capabilities include:

• Scan-to-BIM wizard.
• Extracts point cloud datasets, detects walls, floor slabs, ceilings, door/window openings, columns, and stairs from point groups, and creates native Revit elements inside a single transaction group.

2. Detailed Step-by-Step Usage

Follow these instructions to use the tool in your active Revit session:

1. Select a point cloud instance in a 3D view.
2. Launch Point Cloud to Model tool.
3. Define scan bounds and target categories (Walls, Columns, Floor planes).
4. Set parameters: scan tolerance, element types, and active levels.
5. Click Detect elements to highlight candidate geometries.
6. Click Create Model to generate elements automatically.

3. Technical Specifications & Under the Hood

Revit API Integration

• Key API Components: Point cloud point selection (PointCloudInstance.GetPoints), plane extraction, and bounding box element generation in transactions.
• Transaction Handling: All modifications are packaged into a single Revit API transaction. If any error occurs, the changes are rolled back automatically to preserve model integrity.

[!TIP] Best Practice Tip: Filter point cloud density to run faster element detection. Confirm detected wall thickness with actual scans before building walls.
