When drawing pcb diagram how to judge whether the single or double panel
Single-sided board is generally in the bottom of the wiring, double-panel is in the bottom and top wiring, the default software for the bottom of the blue, the top is red. So, single-panel can only see a color of the wiring
When you are in a wire, you double-click the pop-up dialog box to select the layer where the wire is located
Drawing board is not a judge, but choose a single panel or double panel. Because the price of a single panel is much cheaper than the double panel, so there is no special requirements will try to choose a single panel. But if the alignment is more complex, single-sided can not be achieved when the use of double-sided, or even multi-layer board.
