Glen,
I don't currently draw a floating disk, but to my software the base ring will show as a disk with a certain height regardless of whether it is a floating base or a solid disk. I don't really see a need to go into further detail, but that may change in my new software which I will be announcing soon. The new software does what I call a 5-4-3 process which means that it takes 5 seconds and 4 mouse clicks to create three segmented bowls. It creates a Feature Ring Bowl, a Tornado Bowl and a Painted Segments Bowl. After they are created, single mouse clicks will let you change anything about them including the number of segments, closed or open rings, thickness of rows, placement of the feature ring, the number of Tornado bands, the number of repeating paint units. You can even swap out the palette that contains 10 species of wood for other palettes. All in 3D. :->
I'll soon be making a post about it and hopefully some videos as well. I plan to release it at the Segmented Woodturner's Symposium in Boston in the last weekend of October.
It is not an upgrade as I wrote it completely from scratch using new languages. Woodturner PRO/3DP will continue to be supported as the new software does not and likely won't do staves or compound segments. My goal is for it to satisfy 95% of segmenting needs with a SIMPLE-TO-USE user interface.
