Basically, I have two surfaces (see Rhino file below) I want to connect each point on the inner surface to four points on the outer surface. My end goal is to extrude a truss system from the resulting curves.
I've drawn in some lines in the rhino model to illustrate what I'm trying to achieve
The Three main Components to use here are: Distance, Sort List and Sub List.
1) Measure the distance between each point in first list and every point in 2nd list. (Hint: graft the first list)
2) Sort results and synchronously sort the 2nd list.
3) Create a sub list of the first four items.
4) Connect each of the points in first list (again graft) to the sublist
There is a separate component in the Sets>Tree section or you can use the right click context menu and select it from there. (the context is only available in v0.8)
Where he has a little upward facing arrow, you would have the Graft component.
So, between the flattened first list of points to A in the distance component, and then another between that same list to input A of the line component.
That's really odd. Where you have the output from the distance to the sort component you should have a dashed wire representing multiple items on multiple branches but instead you have a flattened wire. I've re-done this in v0.6.0059 so you can down load the ghx file and have a look.
