What is it you specifically want to know - it's a big area. I
use the NextEngine scanner but I tend to use the scans as a 3D
sketch underlay to create new surfaces from rather than trying to
use the actual scan data curves. If you want to get into semi
automated solid generation you are really looking at additional
software such as RapidForm -

NextEngine sell an OEM version of this that only works with scan
data from the Next Engine scanner. I've not used it but others say
it is very good.
RapidWorks is good, but it's not all that it's cracked up to
be. It doesn't work well on complex geometry. You are basically
using it to "build over" the surface mesh with solid geometry.
Well, I can use Solidworks to do that. It does do simple parts well
enough (those with easily recognized geometric shapes). It does
have some very useful reference geometry tools, such as the ability
to create a symmetry plane (a plane running down the middle of the
part). I guess its usefullness really depends on what you want it
to do. It will NOT instantly convert a surface mesh to a solid.
However, if your surface mesh is complete (no gaps or errors),
ScanStudio can save out an IGES, which can be brought in and
coverted to a solid by Solidworks. This is the method I use most,
but it requires exceptional attention to detail during the scanning
process.
