Create multiple circles using the 3 point method

Hello dear Grasshopper community,

is it possible to create multiply circles (aprox. >1000) with 3 point method in Grasshopper. I will have a list with coordinates (X, Y, Z).I am thankful for any help!!

Greetings

Alex

Hello - if you have a text file, I think you can just feed the points directly from a file component to a Circle component:

Hi Pascal,

Isn’t that just going to give you circles with the same radius, centred on each point? As opposed to circles through three points?

Something more like this maybe:

Assuming the input file can present triplets of points and not just a continuous stream (the latter being more error prone).

Set the File component to the following file (or another file that is delimited like this one):

White group, adapted from a recent post, this uses random points in 3D.

1000 circles gets rather intense!

P.S. I don’t remember why that yellow group looks more complicated than necessary?

Hi Joseph,

I knew there had to be a better way than three clumsy culls - your item component with three outputs is so much more elegant. Thanks!
