I am trying to move a group of traces from one layer to another layer.
I tried select all traces-> right click->Change Layer -> <Choose Layer>
I get this error SPMHGE-510): Connecting pin is not on new subclass.
All I want is the traces to move to a different layer. I already have vias on that layer that would connect to traces.
you can try z copy
Edit --> Z-Copy
then select the clines you want to copy.
after you copy the clines to a different layer, you delete the original clines.
you can change the layer of the clines only if the clines are not connected to any nets.
