algorithmic modeling for Rhino

Hi everyone!

Im currently facing a dilemma with 2 things I want to achieve.

I have 25 surfaces, and want to extrude them negatively and positively. (left picture)

If I input the positive vectors and the negative vectors into the direction input of the extrude I get 50 vectors against 25 surfaces. So the remaining 25 are all extrusion of the 1st item.

I solved it by using 2 extrude components, but that does not feel good enough.

I simply want 2 values to be applied to 1 surface, cant be that hard.

With the other dilemma (right picture) something similar happens:  I wanted to weave the negative and positive vectors, to have one surface extrude in one direction, and the other in the opposite direction, alternating. Thing is I have 25 surfaces and 50 values, again. I believe I need to divide each list of 25 (positive) and 25 (negative) in 2. But thats 12.5 items/values, which is not possible.

I have uploaded the definition.

Thanks

Thanks, that does it!

Any ideas for the weave issue?
