Hi
I am on Altium 23, a 4 layer stackup, signal-plane-plane-signal. All components laid out and time to get started defining split planes.
I select layer 2 and draw the lines to create a split plane. But no split plane is generated. I have tried a lot and tried to figure out why not, but I can't manage. What am I missing?
I tried both drawing a line from pullback to pullback and also to draw an isolated island in the middle of the layer, but everything to no avail.
I noticed that when in 3D mode, the components are shown, but the pcb laminate itself is does not show up. Could that be related. Did I miss something in board planning mode. I mean, the pullbacks are three, right where they should be.
Double clicking on a plane layer does nothing, either before or after I add a split line. It's like Altium doesn't recognize the layer as a plane. But it is set as a plane in the Layer Stack Manager.
Anyone who can point me in the right direction here?
Thanks!
