i have an 6 layer board. Stack up:
For the purposes of checking this, turn the Thermal Reliefs back on, you will then see the spokes, 16.6 will embed the net names in the spokes. You could set the Thermal Relief type with Shape Instance Parameters, select Shape, right-click>Parameters, so that you can see this change for the layers, change the Thermal Oversize for example, you can undo these settings once the checks have been made.
In reply to oldmouldy:
Wouldn't vias have direct connects with no spokes?
In reply to stump1019:
I believe that Oldmouldy is suggesting to turn the thermal reliefs back on only long enough to validate that the vias are connected to the correct copper pours, then turn them back to direct connect. The net connectivity does not change with regards to whether you have chosen direct connect or thermal relief.
