Hi Thom,

You can use the Intersection of BRep component to trigger an event. The output of the Brep/Brep is null if there is no intersection and a line if there is. Therefore if the line has any length then there must be a collision. This true or false value can be plugged into a cull pattern component to either allow the next event or not.

Hey thanks Danny. I was wondering what the best approach would be to pull polylines out of the vectors to a certain length.

Hey Guys I am trying to get some geometry to cut through the lines and it doesn't seem to be working. Does anyone have any ideas?
