connecting odd points of to circles.

Hi all,

I just started with grasshopper so I dont really know what i am doing and i have tons of questions since there is nobody close who even knows what i am doing.

The image down here shows what i am working on at the moment. two circles, devided in several points and then connected. but now i have been trying to connect the generated x-frames with each other (marked black).
Can anybody help to do this? its probably super basic.

Thank you very much in advance.

Hi Marius

If you use a Shift component with your list, exactly as you did before, you can specify the number you want to shift your list. Initialy its value is 1.

See the image :) is it what you want to achieve ?

well there we go. faster then expected. :D
next step would be that i want to push down one side of the construction, so it adjusts itsself eventhough one side is up like 4 meters and the other side is down to 2.
do i do that with a function? it would be perfect if it would be a curvy, smooth movement. have you got a good idea or is the function thing already the right direction?
cheers.

I'm not sure I understand well

Something like on the image, with the upper part in a plane that could rotate around Y axis ?

yea. thats what i meant. the problem is, that i still have the old grasshopper version so i dont have every button you used and i cant open the file you attached. i should get the new one soon. but i guess i understood the principal. :)
Thank you very much.

Hi mms

I think it is your interval which is null, since it goes from 10 to 10. In my definition (though we can't really see it on the screenshot, I'm sorry), I changed the expressions to construct a plane which encompass the circle for sure.

In A input, you can for exemple write the expression : -2*A

And in B input, the expression : 2*B

Cordially,

Rhydro

hi rhydo,

thank you very much indeed. It works perfectly fine and makes total sence with the expressions. I am sometimes still not sure what the most straight forward buttons do. :D
I opened a new discussion but noone really replied. I thought its a thing which many people ask themselves. but i want to wrap a sin(x) function around a circle or along a curve, so that y=0 points of that function always lie on points of that curve.
do you know what i mean? ;)

yours,
Mms
