Domain / Range

I am new to Dynamo and was wondering if anyone can help with a function I’ve been using in Grasshopper.

Having set up an extensive grid of points and a circle (on the same plane), is there any way I can select just those points that fall within that circle?

Many thanks in advance for any help!


Care you share what you have tried so far? images, script, sample files?

hi, can i ask what is Grasshopper “Divide Domain 2” & “Isotrim” in Dynamo?
