A 3D scan is only an element in the production chain. One of the most widely used spheres of application of 3D scanners is reverse engineering. A CAD model, converted from a mesh, is used for downstream applications such as 3D printing or manufacturing.

Most CAD software (Autodesk Inventor, Autodesk Fusion 360, SolidWorks, Solid Edge) don’t have mesh-to-CAD support. Geomagic Design X was specifically designed for mesh-to-CAD transformation and provides powerful tools to achieve that result.

It is generally accepted that mesh-to-CAD conversion is tedious and hard. To fight this prejudice, I made a tutorial on practical application of 3D scanner Calibry in reverse engineering. I tried to highlight not-really-obvious stages of mesh-to-CAD workflow.

If you want to try the same thing as in the video, you can find links to the mesh and CAD model down below:

Here you can download the .stl mesh

Here you can download the CAD model.
