I’ve previously been able to draw copper zones by snapping to magnetic points on pads (i.e. corners, midpoints etc.).
Despite having all magnetic points set to “Always” in Preferences, Grid Overrides enabled (Ctrl + Shift + G) and snapping set to all layers (Shift + S), somehow this behaviour is no longer working and I can’t get a copper zone to snap to the edges of pads.
Interestingly this only seems to be when drawing a copper zone on the bottom layer. When I move back to the upper copper layer, the ability to snap to centres of pads returns.
