Thank you again @Ewan_Opie! Will have a look to see if this accomplishes the same when I am with Dynamo tomorrow! I was already using the View3D.SetSectionBox node from rhythm in my script, as pictured in the first image in my original post; I’m hoping whatever magic you’ve included in the .dyn will be a solution without having to first get the section box geometry via Python as I was attempting. It is very typical of me to try and create something within the narrow scope of my existing knowledge, before trying to find solutions from others. I appreciate this and will let you know if it does in fact achieve the same outcome that I was looking for
