Creating freeform surface from curves list

I am making some GH samples to be opend.

How can I create freeform surface from curves list?

In GH 4ptSurface works from the curves list, but I cannot with Sweep2.

Please see the attached GH and Rhino model.

Process is easy, read surface from Rhino and offset, then divide them with UV number.

Also divide offseted exploaded surface with UV domain definition.

Then get curves info from them for Railsweep and create lines as section

Thank you!

Atsuo,

You are almost there, but you should maintain the data structure (instead of flattening) to help you use [Sweep2Rail].

This might be a little sloppy since all the path names going into [Sweep2Rail] are different, but it is working.

Hi Taz,
I have not figured out using marge component for section curves.
Thank you very much. It's great help!

Atsuo,

Technically you don't need to use [Merge]. If the path names are the same, the items will automatically combine.

The benefit of using [Merge] is that you can visually see the order in which path items are combined. The items from branches in the A input will precede the items from identical branches in the B input.

If you don't use [Merge] the order is based on the attachment sequence to the Rail input.
