Is there any way I can loop the nodes? For example, I need to some complicated work for each pipe of a selected pipe network. How can I create a loop to do it?
Hi @DavidFan74,
Looping in a visual programming context is a bit tricky. In many cases though, you don’t need to think too much about looping. You can just provide a node with a list and it will process all the items. In some really complex cases it might be simpler to write up a quick Python node to handle the looping, but most of the time that isn’t necessary.
If you can share a little more about your goal, we can figure out a way to hook everything up.
Yes, generally no looping needed. This case is odd. I’m trying to find all the crossing points for selected pipes to a pipe network. If I use the list of the pipe network pipes directly, it gives me 2 empty lists. If I use only one pipe from the network, it works. That’s why I’m thinking of using looping to check each pipe in the list. I’ve attached the script below. Thanks.

Have you tried cross product lacing? Basically, “intersect each pipe with every other pipe”.

Yes, “cross product” works.
