Hi Michael,

I'm not going to keep flogging this dead horse: I just wanted to make a final proposal.

After selection of the item to be flowed, the dialogue box would prompt "select base curve, surface or point cage".

If point cage is selected, the software expects that the flow targets will be an inner point array and outer point array.

I think this approach is consistent with the MOI philosophy of limited suite of tools with multiple functionality based
on input. (why have a specific tool for each of "Flow Along Curve", "Flow Along Surface", & "Paneling Tools", when
they could be folded into a single powerful tool: "Flow").

It is just a thought.
