Moving footprints to opposite side of board bug. (1 reply)
In ExpressPCB Plus you need to have the bottom silkscreen turned on. You can do this by selecting Design Info at the top then Board Properties. Then put a check mark in the Bottom Silkscreen. ExpressPCB Classic does not support bottom silkscreen however you can import your classic file in to plus to add bottom silkscreen.
When I move a component from the top to the bottom layer or vice versa the silkscreen parts of the component get converted to copper layer.
