I'm working on a board, but one of the pins keeps getting connected to ground even though it is not in the GND net. It displays correctly in the EasyEDA design screen: ![PCB as shown in design tool][1] The image shows the top two pins (correctly) disconnected from the rest of the bottom layer ground plane. But if I use the Gerber viewer to view the board I get the following image: ![PCB as shown by gerber viewer][2] Notice that the top right (top left from the front) pin hole appears to be connected to the bottom layer ground plane. What's more, look what happens when I try to work around this by drawing the bottom copper area around the problem pin. ![working around the problem pin][3] ![problem jumps to the next pin][4] Notice how the problem jumps over to the next pin that still remains inside the copper area? I think there must be some problem with the way that the pcb design software is outputting gerber files. Perhaps it is forgetting to properly close a shape when drawing on the copper voids in the area?
