| Would that be an approach for making the cut-out for an undermount
This method works well for irregularly-shaped objects. For more
regularly-shaped (ellipsoid or rectangular) it's usually easiest to
make a few measurements and type in the program.
| Take the sink, and trace it? Is there enough Z to get a sink under,

You can have as much Z as you're willing to pay for. <g>
There's no real reason you couldn't make a hole in the table - but by
the time you've built and surfaced a table, I'll bet that you won't be
eager to chop it up...
There's really no need (I'm guessing) to get your spindle /over/ a
sink. Just turn it upside-down and trace whatever contour you're
interested in. If that contour is too high for your Z, then turn the
sink right side up.
| Many sinks come with paper templates which can be scanned at a blue-
| print shop, then digitized from there?
You can. I'd just take a photo and import the JPEG into my CAD package
and trace over the image - then delete the JPEG and save my drawing as
a DXF (which the ShopBot software can understand)
More and more manufacturers are making DXF files available for the
asking. I've got CD's on my desk from DeStaCo (clamps) and Charlotte
Pipe and Foundry - with both 2D and 3D drawings. Check with your
favorite sink/faucet manufacturers - they may have already done the

Yeah, sure. <eg>
