Splitting a plane layer howto videos?

[analognoise]

Hi all,
I'm using AD to create an FPGA board, and I need to either draw a polygon pour and use a signal layer or use a power plane with a split. I think I've managed to get the polygon pours correct, but I haven't managed to stumble into getting the plane layers to split.

Sorry if this is a very amateur question, but I've had a go of it for a while and can't make it move, if you will.
Thanks!

Go to the plane, simply draw a line where tou want to split (place track) and altium will split it. Its that easy.

Shoot, I was selecting "Interactively Route Connections" rather than drawing a regular line.

Works like a charm now. Thank you very, very much!
