Just went window shopping for that Artec scanner, not in my league, as in 14.5K used. I did find this this very funny review on Amazon: "I had to sell my child for this unit but it was totally worth it. I went to the person who bought my kid and asked them if I could make a 3D scan of him. Now I have the best of both worlds! I am just waiting for the Holo-deck to come out so that I can upload my kid to the matrix" Steve, while that scanner is out for me at least, what software do you use? Maybe that's available reasonably or thru a class at my local CC.

Steve,
With scanning, are you using unmodified mesh data to make sections or are you having to redraw the surfaces to get good enough quality to section?

I typically resurface for large objects like cars. the nature of scanning in polygons... curves cut through here are really segmented lines... and sometimes there are errors that need to be manually interpreted after scan alignment.

Rhino Nurbs made over scan mesh data... mesh data isnt showing here.

Something to take into account is the thickness of the individual station, while I was working on my cobra buck all 13 shts 8x4 ply I had a discussion with Kerry on where would the collected data pass through the station. Initially I thought the centre but that would mean in some section material is missing.

Thanks Steve,
This is what I've assessed is the situation with scanning, the scan data is really just a template for someone very skilled at interpreting the mesh and who knows the software to a high degree and redraws the shapes. The impression people get is that the scan is ready to slice and dice into an buck, it is possible, but the quality of examples I've been given don't give smooth accurate profiles, they need to be redrawn to get them right, as you said. Learning Rhino or any other surfacing software to your level must take years, even if you use it everyday, very similar to learning to shape metal or weld. I'm learning Rhino and learning the tools and procedures to accurately get the shapes you want is not easy, because you have to understand how surfaces are best drawn, if you get it wrong they never blend properly when you use the Zebra lines to analyse connecting surfaces. Plugins like TSplines help the less skilled operators create smooth shapes quicker, but you still really have to understand where you are going. If you are paying someone to redraw a mesh, I'm sure it would cost quite a lot and rightly so in my opinion, as it's a real skill in its own right.

Great info.
Im still waiting to get a quote for my scan. Sounds like the scanning is the easier part, the processing is the harder part. I was thinking of buying the scanner and doing it all my self, im thinking again now
