Laser Scanning
(OP)
We are considering the purchase of laser scanning equipment. If you have experience in the selection and use of the same to ultimately get to a solid model in UG, your insights would be appreciated.
So far, we have only looked at the Minolta Vivid 910 scanner and GeoMagic Shape Studio software.

UG in itself is not suitable for that, Imageware yes but that is more compleks software that is used also for free form design etc.
GeoMagic is strictly reverse enginering software, after you create the surfaces you can export for UG or any other software.
As far as the laser scanin device I need more info for giving you an opinion, like what products do you have to scan, what size, and what tolerance do you need to reach.
Do you need a mobile scaner or a fix one. Without this information I can not give you any specific answer.
RE: Laser Scanning
Sould have done that up front.
The primary products we work with are castings. Most will will fit in an envelope of 6x6x18 inches. Most of our dimensional tolerances are +/-.030 and +/-.015. Rarely there is a +/- .005 dimension. There is no need for portability of the equipment.
So far we have noticed that the output surfaces contain numberous "self-intersecting geometry" errors. With some effort, the number has been reduced to the range of 15-20 such errors. Another difficulty presented, is that none of the surfaces appear planar.
As always, any thoughts are appreciated.

It looks pretty good and we usually get a xyz point cloud and a stl from them.
What we do is create a model in UGNX2.

Check out this site for some good information on the scanners

There a distributor of white light scanners

I have utilized Imageware and also GeoMagics.
GeoMagics is FAR easier to use and get usable surfaces. Imageware was extremely TEDIOUS to get any results.
Finally, the cost of GeoMagics is much more reasonable.
Just my $0.02.

The optigo I believe has 3 cameras compared to the other scanner which has only 2. Our customer says this is better.
larrycoyle,
How does the Highres Industrial work? Is the software for scanning or for manipulating stl files withing UG? Right now, what we do is cut sections along the stl, cut another section on the curves to generate points that have a regualar pattern, the create our surface by using "from point cloud" in UGNX2
