Hey Brian,
Thanks again. I have all of your scripts and commands.

Regarding this one and generating a solid, is there any information on creating a smooth result?

Meaning, your curves iteration doesn't end in tangency, and produces little dimples on the ends....

If the last 2 points on each end of the result curve were g1\linear or planar, then the revolve would be perfectly smooth.

I just don't know enough about these types of math equations to know whether looking at that changes it from an eggovoid and breaks the intent....

Anyway, just some food to the discussion...
