How is size calibration handled? Do most scanners work out the real-world physical size of the object? Or is there some way to calibrate a mesh to its real-world size based on two known points (like we do with canvasses)?Īny insights or thoughts would be greatly problem is you want to buy an optical scanner so your scans will not be 100% accurate.

But I can't find any info on this new functionality. Is this true? That's exactly what I want, as if I can get the basic curves of a scanned geometry, some basic extrusions and lofts will give me a parametric version pretty easily.

I saw in a YouTube tutorial someone offhandedly reference that there was a way to divide a mesh (in the new Mesh workspace) up into planes/sections of that mesh and use it to create splines that give you the contours of the mesh.

Perhaps this has increased since I read the number, but I remember thinking it was much smaller than most 3D scan poly counts.

I remember reading there is a limit on the number of polygons a mesh can have for import into Fusion.

I'm just a hobbyist, so I'd rather not drop that kind of money unless I'm pretty confident I can use it to achieve my purposes with Fusion. Does anybody have experience doing this kind of thing with Fusion 360? So a 3D scanner seems like a good way to capture those curves without having to physically cut the original parts, trace the curves in 2D, and then scan and trace into a Fusion sketch.

The parts I am reverse engineering often have complex spline-style curves, which I can't just readily model using my trusty old caliper and bevel protractor. The parts I want to model are mostly injection-molded plastic shells for things like consumer electronics, but I want to end up with a parametric model rather than just a mesh. I am currently investigating purchasing a 3D scanner to help me in creating CAD models of existing parts.
