Thanks Karsten

RE: Loft2

That does the trick. Brilliant

RE: "A checkbox would be better"

or even better a pulldown menus for each of the options built into the node.

In the meantime, I think Inputs for each of the settings (Closed, Cap Ends & Styles) would be useful, or at least more explicit.
This could be paired with a new "String" node for entering strings such as "Normal" "Loose" or "Straight"; while the other options
could be dynamically set by logic/math nodes. That way where required settings are visible in the wiring diagram.

But this new loft node suits my purposes very well.
Thanks again
