What is 3D Scan to CAD?

Reverse engineering services, part digitization, and 3D modeling are three fundamentally linked processes. To be able to provide services in one, you must excel at all three.

  • 3D scanning is a technology used to collect a 3D data set of an object or part. The digitization process captures the exact shape and size of a part without need for destruction of the part. The data acquired is used to construct a 3D model.
  • Data processing is a pre-processing step to get ready for creating a 3D CAD model. Raw data is processed with specialty software to create a polygonal .STL model.
  • CAD model creation can involve a few methods. The first is to convert the .STL file into a .STEP file. The second method is a completely surfaced model that matches the scanned part exactly. All imperfections are included. Lastly, the surfaced model can be exported in IGES or STEP format for further processing in other CAD software packages. This method produces a simple solid conversion of the polygonal .STL file. No parametric information is contained in the file.

Computed Tomography (CT)

Computed tomography (CT) scanning or industrial 3D imaging is the most advanced 3D scan to CAD technology in the metrology world. CT is excellent for critical components that have internal geometries that cannot be fully inspected with any other 3D scan method.

Structured Light (Blue Light Scanning)

This light-based, non-contact testing system is great for reverse engineering applications, prototyping, and quality assurance. The blue light has a narrow wavelength and is not as prone to ambient light as its predecessor (white light), giving you a more accurate scan.

3D Scanning

When looking for 3D scan to CAD services, it is important to consider the 3D scanning equipment being used, the technicians’ level of expertise, and the software that will bring the best level of interrogation possible. At Nel PreTech, you will find all three and the consultation to help you decide what 3D scanning platform is best for your project.

Where is 3D Scan to CAD used?

3D scan to CAD can be ideal in any industry looking to better a product, duplicate it, or learn from the design. The personnel conducting the scanning and modeling are highly trained and experienced in both disciplines.

Industries that use 3D scan to CAD services include, but are not limited to:
