How to select the same face from different breps?


I want to select the same face as i am selecting for all the breps, I tried with split list but it went wrong. It looks silly but i am struggling with it and couldn’t find answers in my researches…select (147.1 KB)

select (154.7 KB)

Edit the SrfDir cluster to see how it works.


nice! thanks man, amazing component! should be on a grasshopper update! Is there a way that i can have it as a component/command?

In Grasshopper, select the cluster and then ‘File | Create User Object…’. It will be in the ‘User’ tab.

In this model, it will find the top and bottom surfaces but get goofy with the cylinder walls.
