3D scanners for CAD provide high accuracy, save time in creating 3D models, capture complex geometries that are difficult to model manually, and facilitate reverse engineering processes. They also enable easy modifications to existing designs.

3D scanners typically output data in formats compatible with CAD software, such as STL or OBJ. The scanned data can be imported into CAD applications for further editing, analysis, or integration into larger projects.

The best types of 3D scanners for CAD applications include laser scanners for high precision, structured light scanners for detailed surface capture, and handheld scanners for portability and ease of use. The choice depends on the specific requirements of the project.

Yes, 3D scanning can significantly reduce the time and effort involved in creating CAD models from scratch, especially for complex objects. However, traditional methods are still valuable for certain designs where precise control over dimensions and features is needed.
