Hi Burr & Ralf - most of the time CSec is not really needed though, just directly loft the guides with one another using the "Closed" option.

So for example with these 4 guide curves:



Instead of using Csec to set up many sections, just select all 4 and use Loft and hit the "Closed" checkbox, it will make this result:




CSec is just kind of an extra step to go through that is not really needed normally.


You can also draw curves at the ends and use Network as another way too, like this:




If you like the way CSec works, then certainly that's fine, but it will probably take longer than these other ways.
