What is a piperouter? How do i find it?

Hi guys

I recently used the lava effect that fusion has installed and i seem to notice that there was a little curved circle in the "flow view" and it had the name of piperouter

Is this a checkpoint to let you know that everything connects in the certain area, just so that you won't be lost?

Also, how do i find it? How do i put it?

Please help me
Thank you thank you so so much

the piperouter is just a little helper to keep your flow organizied, it is a "elbow" in the connections to the nodes

you can create one when you "alt+lmb" click on a existing route/pipe

Thanks a lot mike

Besides the shortcut,
Can it be found in the tools section?
