I have a fill in layer 1 but I cannot fill any other layer. Here I show two fills that are in net GND1 with each having a via that is in GND1. I also tried running traces.
There needs to be some connection to a pad of the given net. So your traces ending nowhere will not do the trick. See How to create a power plane (using zones)

Just saw this happen in front of my eyes elsewhere. The thing is that I thought that a ground pad via is also a pad. Weirdly, the other fill also went in because it was connected with a trace to the component. Why is a via pad not a pad for fill purposes? Anyway, as a new-ish user I got burned 3 times by fill befuddlement. Another time it was because my fill did not cover 50% of the pad. I think it would be nice if there was some more fill feedback, like every time a new board is created when you do the first non-fill a popup emerges giving all the reasons it’s not filling:
warning: no fill because
- vias are not pads
- the 50% coverage thing when the component is on the same layer and no trace
- fill area must be connected by trace to pad that matches the nets
Thanks for your tolerance. I did look around first but I thought a via was a pad
A zone must be directly or indirectly connected to a component pad. That’s logical because pads correspond to symbol pins which form nets when connected together, and component pads just reflect the schematic. If a copper area isn’t connected to a component pad it’s necessarily isolated from the net.
