A constant distance between circles

Hello.

I need to control the distance between two or more circles in Grasshopper, so there always is the same distance between the circles.

So if I change the distance (slider) the circles move closer or further away from each other, they allways need to have the same distance between each other.

How can I solve this in Grasshopper?

Hi Marie,

Something like this (see attached) ?

Thank you very much. It is like that. But what if I want to placed them in for example in a triangle and not on a straight line?

It's as simple as joining the same value to a x and y vector component. I've attached the definition again.

Thank you very much!

Oops, sorry, I missread that post.

what you actually want to do is move the circles in the x and y direct proportionally so that all circles are equidistant right?

I've attached a corrected algorithm.

Yes, it looks good, it is something I can use.

Maybe you can help me with another question?

I have a city with buildings and I have found the volumes of the building. Now I want to show a difference between with colors, so the volumes over a given value have to by one color and the volume under a given value have to by a second color.

So I have made a “Split list”. But I don’t know how to make it to a geometry because the output is Volume, and how can it be a geometry and get it back in my system, so it can be showen as buildings?

Is this even possible to do like I am?

Use the dispatch component to dispatch the buildings according to their volume. then use the preview component on the output.

Sorry but I am just started a using this program. So I don’t know dispatch very well, I have just used one time. So when I am trying it gets red, and I don't know what to put in P?

There's two ways of doing this.

The first dispatches the result in two lists.

The second uses a domain include to create multiple lists (say volumes between 0 and 10 are a color, 11 to 20 are another color and so on.) To achieve this, just copy everything past the volume component and change the upper and lower values accordingly.
