The Scan to CAD conversion process involves transforming raw point cloud data captured from 3D laser scanning or photogrammetry into an accurate and editable CAD model. This process is essential in architecture, engineering, construction, and manufacturing for documentation, renovation, and design purposes. Here’s a step-by-step overview:

1. Data Capture:
   The process begins with 3D laser scanning or LiDAR scanning of the physical environment or object. The scanner collects millions of precise data points, forming a point cloud that represents the geometry and spatial details of the surface.

2. Data Registration and Cleaning:
   Multiple scans are aligned and merged to create a unified model. Noise, unwanted objects, and overlapping data are filtered out to ensure accuracy and clarity.

3. Point Cloud Processing:
   The cleaned point cloud is imported into specialized software such as Autodesk ReCap, Leica Cyclone, or Faro Scene. Here, the data is further optimized and prepared for modeling.

4. CAD Modeling:
   The processed point cloud is then used as a reference to create 2D drawings or 3D CAD models in software like AutoCAD, Revit, or SolidWorks. Depending on the project requirement, the model can be as-built, as-designed, or surface/solid-based.

5. Quality Check and Verification:
   The final CAD model is cross-verified against the original point cloud to ensure dimensional accuracy and geometric fidelity. Any deviations are corrected at this stage.

6. Delivery and Output:
   The completed CAD files are delivered in the required format (DWG, DXF, RVT, etc.) for use in design, planning, or fabrication.

Overall, Scan to CAD London provides a precise digital representation of real-world assets, enabling efficient redesign, documentation, and maintenance workflows.
