It sounds like the problem you had was too many points along the involute and the waterjet stopped / started before each point.

If anyone is interested in the math, I posted a spreadsheet in CD Media that creates a file to import gears into Pro/E. (It only does full fillet gears - sorry but flat root gears are against my religion.)
I'd be interested to give this a try, could you have it export the data in .txt for Solidworks?

Or into something else that more CAD packages can read?

Thanks,
