Hi.

First of all... thank you for an awesome tool. Coding is not my strong suit, so this visual node based tool is amazing, however I am still challenged by it. How would I go about removing all geometry outside the rectangle in the attached image?

Thank you.

   Hi Thomas

   This will be possible with the Compound Node
   take look at my Node Tree which is attached

   As far as i know there are also a Mask Node from Johns
   Node Library he is the Forum Admin.

   Search for "Cartan Node Library 3.3" in the Forum
   the Library have many useful custom Nodes
   all made by John

   have a nice day

   Thomas,

   It turns out that removing all the geometry outside of a boundary can sometimes be a surprisingly hard problem.

   In this case, as Gottfried said, a compound node will do the trick. You need to set the compound node's Function parameter to Intersection. You also need to colorize it afterwards to remove the fill.

   OR you can use a Clip node from my Cartan Node Library - see attached screenshot and demo. Clip will work with almost any geometry and will preserve the original coloring.

   Happy Nodeboxing!

   Hi Gottfried and John.

   Thank you for the responses. I had already tried the compound node but couldn't get it to work as I expected it would. With your help I now know it was because I didn't use the colorize node after the compound node.

   Thank you once again.
