No, but I can recommend an expensive service for scanning major plant.
This is an emerging area I am interested in, and I realised the other
day that a really rich modeller would be able to make most existing
things at any scale by a) Laser scanning the subject (a steam engine,
your beloved, or even the missus) b) Using the so-called 3D printing
to make a physical prototype at any desired scale, c) Making a
silicone rubber mould, d) using the mould to make a wax replica, and
finally e) Investment casting the finished object.
Armed with that lot you could scale model almost anything and in quite
impressive detail, sadly my personal budget will not stretch to such
exotic techniques, and my work only involves big-scale petrochemical
plant.

I've seen the results of that type of scanner. At the scene of a faked
RTA a traffic cop set up a device on a tripod, after a few minutes
moving it to a 2nd then a 3rd location. It created a 3d image of the
entire scene showing the exact positions of all the vehicles involved
which he was able to rotate & view from differant points.
I think what I'm looking for is someone with a NextEngine type scanner
that is happy to do odd jobs.

Good point - I want to use the same technology to scan ladies before
they go flabby. Though I am probably a bit late in life - but maybe I
can market the idea to younger people and be involved in quality
control.
One problem is registering the scans from different positions, so I
expect the copper will have inserted balls (spheres) in various
locations. These are identical when scanned from any angle, so allow
you to lock scans from different locations together without needing to
survey the location of the scanner.

Funnily enuff, when researching laser scanning thru Google I came across
a sculptor with a huge 10'+ 4 axis CNC mill. Scans a person, touches it
up a little, converts it to CNC GCode then his 4 axis mills it out of
some kind of foam . . . et voila' a pattern for a cast statue within a
couple of days.
I reckon there are enuff vain & wealthy people around to earn good money
from that !

I remember a lot of lime green squares, like cats eyes dotted about the
scene but the merging of the scans seemed to be automatically done by
the software.
