Gnd net seperation

[rodster]

I have an interesting problem. I have finished routing a PCB and now the engineer whats to seperate the gnd into 3 different nets. Gnd, chassis, and black. My problem is how do you split the net without unrouting? Can this be done?

Thanks

Certainly. In ECO mode, select the one trace that connects the groupings of grounds and delete it. It will prompt you for a new name for the new net.

If you are using planes, then it will be different, but since you mentioned unrouting I am assuming that the ground is routed on the board.

Thanks for the reply. I'm using planes for seperation. My problem is that it's gnd net and I don't know how to split it, and keep the vias and tie it to the right plane.
