Curves to Solid Object

Hi guys,
I’m in trouble to create a solid object from a set of curves. What I need is :

  • How can I create a loft which is close to the last item of curves?
  • How can I create a solid object from a set of curves?
    Any help would be greatly appreciated. Thanks in advance, guys !

the loft O input has options. You can right click it to get to the options or use the loft options component. In there you will find an option for a closed loft.

Thanks Michael Pryor. And how about my second question? Do you have any idea, bro ?
