Definition
Scan-to-CAD is the process of converting a laser scan of a real object or space into an accurate CAD drawing or model. It captures reality as a point cloud, then turns that data into the precise geometry used in computer-aided design.
This lets designers and engineers work from the true dimensions of something that already exists, rather than relying on old drawings or manual measurements. It connects reality capture with familiar CAD workflows.
In simple terms, scan-to-CAD turns a 3D scan of a real object into a usable CAD drawing or model.
How It Works
The process starts with laser scanning the object or space to produce a detailed point cloud of its actual geometry. The scan data is cleaned and aligned into a single accurate dataset.
Using the point cloud as a reference, a drafter recreates the geometry as CAD lines, surfaces, or solids that match the real shapes. The result is a precise CAD file that reflects the object exactly as it exists, ready for design or documentation.
Applications
Scan-to-CAD is used in manufacturing, engineering, architecture, and heritage. It supports reverse engineering of parts, documentation of existing conditions, design of modifications, and recording of objects, wherever accurate CAD geometry of a real item is required.
Benefits
- Accurate CAD geometry from real objects.
- Reliable existing-condition data for design.
- Support for reverse engineering.
- Fewer errors than manual measurement.
- A bridge from reality capture to CAD.

Frequently Asked Questions
What is scan-to-CAD used for?
It is used to turn real objects and spaces into accurate CAD drawings for design, documentation, and reverse engineering.
How does scan-to-CAD work?
An object is laser scanned into a point cloud, which is then used as a reference to recreate its geometry in CAD.
How is scan-to-CAD different from scan-to-BIM?
Scan-to-CAD produces CAD drawings or models, while scan-to-BIM produces information-rich BIM models of buildings.
What is the output of scan-to-CAD?
The output is a precise CAD file that matches the real object or space that was scanned.
