Hi Andy,

in addition to Michael's post, here is an reverse engineering approach in Geomagic Freeform:

1- Create a smoothed out, healthy mesh to work with in GOM Inspect.

2- Create a thickness to the mesh in Rhino, otherwise it won't import into Geomagic.

3- Draw boundary lines for your patch layout. These lines can be "fitted" to the voxel mesh.

4- Create patches step by step.

5- Export patches as STEP files, so it can be used in parametric CAD Software.

This is how i worked in my former company. Please remember that Reverse Engineering is very time consuming.

Best regards

@ PILOU:

The " Skin Surface" Tool is amazing.

I tried it out some years ago. Unfortunately, they don't sell it as a standalone function.
Otherwise, it would be a great addition to one's toolbox.

QUICKSURFACE is also a good option, it costs around 4,000 dollars.
