How do I extract useful surfaces/shapes from 3d scan into CAD?


How do I extract useful surfaces/shapes from 3d scan into CAD?

I want to 3d model and print a new, modded mouse base for the Logitech MX Vertical. I’ve gotten a pretty good scan of the important parts of the mouse base, but I’m struggling to figure out how to get useful information from GOM Inspect into Fusion 360.

I want to accurately represent the edge of the mouse base (red line) and the screw holes in CAD (circled). None of the other inner details actually matter here.

In GOM Inspect I’ve been able to fit cylinders to the screw holes, but is there some way to get the exact coordinates relative to the origin point I defined? Only way I can figure out is to use the calipers repeatedly to get X/Y/Z of the outer edge of the cylinder.

Then I’m stumped as to how to capture the outer edge of the base where it meets the other half of the mouse. I think I can get GOM Inspect to fit a curve or a surface somehow, but not sure how to export that into CAD.

The interface between the two halves of the mouse is an angled plane if that helps. Maybe I can orient the scan so I’m looking normal to the plane, screenshot it, then recreate it in Fusion with splines?

Or maybe GOM Inspect isn’t the right tool to use? Open to any workflow that seems viable. Thanks!
