Split ground plane (1 reply)
You place a keep out, just turn off other layers and show the layer you want the keep out on. Then at the top under shapes select the layer in the drop down and then select Rectangle on the left. Then at the top under shapes again select the drop down and select Keep Out Fill and draw a rectangle where you want the keep out. You can also do a Keep Out Outline.
Using ExpressPCB Plus, Is there a way to split the ground plane so that I can separate analog and digital grounds? (Appropriately joined with a ferrite bead at a single spot, of course).
