Gradient Extrusion

Hello Wonderful Grasshopper Community,

I'm having a bit of trouble realizing something in grasshopper. My intent is to create a mixed use tower where the floor-to-floor heights change from about 12' (for office) to 10' (for residential) throughout the course of the building. I was hoping to use the gradient tool to inform the floor to floor heights such that the red would be 12' floor-to-floor and the blue would be 10' floor-to-floor, with the purple being kind of a random mix between 12 and 10...I wonder if any of you could help me with this endeavor as I can't think of a practical way to set up this definition. Any help would be great even if you could just point me in the right direction, it would be much appreciated!! Here is the file so far if you guys want to take a look!

i saw the values of your coloured list, and if you look, there are 15 floors red, then 30 with the gradient violet, and 25 blue.
so i just tried manually...maybe you need something else.
last thing i didn't (to assign colours to paths in data trees), i will look tomorrow maybe.
it helps?

pd.oh, yes, i tried to make a range from 10 to 12 and assign to the violet one...didnt work.
will also try tomorrow.

Ah I see what you're doing here, this might work a bit better than what I was trying to do, I will fool around with it tonight and see what I can get, and post back tomorrow with the results!

P.S. Thanks for your help!!

Donald,

If I'm understanding you correctly you want to create a gradient condition using either 10' or 12' floor to floor heights. If this is the case try working with boolean lists to select one of your two options.

Taz thanks a bunch, I think the boolean list within a domain range is definitely what I need to look at, I've got enough ammo to do some damage tonight, I'll post the results tomorrow, you guys have been super helpful!

So I ended up going with Taz's solution in the end and it was pretty successful, However now that I have the different floor-to-floor heights is there a way to re-evaluate the Move in the Z direction so that each floor is ~2' apart from each other? Here is the file so far.

ow! i didnt understand everything yesterday.
anyway, looks better, but still floors in the middle take 12 of hights even if later you extruded by 10 or 12 randomnly.
see what i mean?

I think I see what you mean...the overall move of the original curve is 12 from the beginning of the definition, which is something I want to somehow change or re-evaluate so that the extruded surfaces have 2' between them...a problem I haven't figured out a solution to yet, but I'll get there.
