POINTS CONTROL ON 'WAVIE' SURFACES - UNRESOLVED PATHS NEEDING RESOLVING...

Hi all,

I am a novice to Grasshopper and currently trying to get my head around it.

I have some queries if any one is willing to help me out please.

First question - I have double skin facades I would like the list of starting points and finishing points to be the same and on the curve that created and similarly in between the different 'sections' of double facades I would like the 'column of points/edges of surfaces' to start from the same position. Basically the facade should have some fixed points and behave like boat sails (I hope what I am saying makes sense).

Second question - I would like the top points of the single facade to decrease as you move away from the central core of the building (the one formed of double facades). Is there a component that allows me to do that or do I need a sequence of component to be able to do that?

Third and last - How can I link the 'internal floor slabs' of the building to the bottom curves created by the new surfaces (and not the starting curves) please? So if the double facade changes also the floor slabs should change instead than changing based on the graph.

Thanks.

Riccardo
