how to extract information from previous node

hi guys

is it posible to extract information from a node which had multiple inputs and thus
stores an array of results?

like in the attached image.

I have a loft surface, I created 4 points (U/V = 1)
as you can see the line out of the subdivision node is dashed .
What does that mean?

How can I extract the info of each point so I can attach each point output
into a new individual point node?

Also lets say I have 2 surfaces cut with 1 surface.
I calculate the intersection curves. how can I extract the curves with with only using one intersection solver node?

Hi Claas,

the dashed line means that the data that flows through the wire consists of multiple lists. The Surface Division components creates multiple lists of points, namely a unique list for each column in the grid. If you divide a surface into 4 points (2 by 2), you'll get two lists of two points each.

What do you mean by "info of each point"? The coordinates? If you have a list of 4 points and you want to split the stream into 4, you'll have to use the [List Item], [Tree Item] or [[Graft] + [Explode Tree]] components.

You should use two separate components if you want to perform two separate intersections. Merging data is only a good idea when you are prepared to deal with a combined data structure. Merging is easy, splitting is hard.

Hi David,

we are exploring how to use GH for seat shell designs.

The main problem is who to model a thickness which can be
changed afterwards.

We build curves which are lofted and than provide the contour of the shell.
That surface is offset.

Than figuring out how to get the sides filled is the tough part for us.
