I want to make a plane for my supply on my PCB and a plane for my MCU to isolate the MCU from the power supply noise.

I found this article in Altium designer resource:

But it isn't clear how the split plane tool work. Can someone explain it in a different manner?


This is a picture how I see the planes: enter image description here

  • \$\begingroup\$ Defining the region, I can't properly set the internal plane. \$\endgroup\$ – MathieuL Jul 6 '15 at 19:16
  • \$\begingroup\$ easy.. just draw a closed shape and double click it to tie a net \$\endgroup\$ – hassan789 Jul 6 '15 at 19:20

  • \$\begingroup\$ Yes, with the polygon pour tool I think it is possible. \$\endgroup\$ – Bence Kaulics Jul 7 '15 at 13:59

Click on Place Polygon Plane ( enter image description here ). On the dialog, in the Net Options select the specific net to which your component is connected.

Then draw the desired shape for your polygon(s).
