Almost certainly, you will need to use software to process the scan-data
into a format suitable for JewelCad. If you want polynomial
(spline/nurb) surfaces
then you might consider:

- surfacer (from Imageware). it offers a broad toolkit, and has good
tools to go from a scan cloud, to nurb surface model. Prices depend on
what you get.

- surface studio (from Alias Wavefront). This software features
excellent tools for creating surfaces, and can handle large scandata
data sets.

- paraform. This is a new company/software that has strength in
integrating scan views, but has some ability to surface the data. I
have not seen this software in action.

- I believe Delcam's ArtCAM has capabilities for creating artistic
surfaces. Delcam also has a design module, and a machining module
capable of handling the large quantities of data that you get from

- geomagic wrap (from raindrop geomagic). This software's capabilities
are primarily related to creating polygonal models from scandata clouds,
but I believe you can slice them to extract
iges spline section profiles.

- Innovmetric's polyworks. This software is good for scan-view
integration and polygon model building. However you can build
polygomial surfaces on the models, and export them as IGES.

?brockware? might be able to transform between different surface
representations in IGES files.

However if you have point-cloud, or polygon-cloud data from a scanner,
you currently need interactive tools to build a surface model from this
data, and those tools need to be able to handle large quantities of
(point or polygon) data.

By the way, Hymarc make a laser scanner you might consider.
It offers fast data, dense data acquisition at good accuracy. Check out
our web site, or contact me at the coordinates below.
