I got an old Nextengine laser unit and some geomagic software tied directly to that model a while back and tested it out for a week or two
I only paid a few hundred dollars for the lot but the original full setup bought by universities etc would have been around $30,000, most of it for the geomagic software.
Well I really struggled to make it work and abandoned my efforts after a couple of weeks because I just couldn't make it work for me, and most jobs can be solved with a good set of calipers.
Plus some of the file useage was massive and even my six core computer was taking ages with GM

Anyway. I came back to the STL files with a bit of MOI under my belt and looked at improving scans via MOI and I reckon this is the way to go for us poor people and it's far simpler.

You can use MOI to build the scan into sensible parts, the first part you have to do is the "Origin" part and then you build the other sections around that part to achieve proper squareness in three dimensions

I've done hardly anything on this stuff, it's been a whole new area of learning but the geomagic part for me was abandoned pretty quickly

So my recommendation for a cheapie 3D setup is get a scanner that does good STL files, and use MOI to orientate/Build your result into a full drawing

for stl/stp stuff I used Alibre
