![]() | Some pcb needs a ground plane, conductive or shield type, or
with outdrawing the signal tracks.
The two images above shows two ground planes that are different only for the
distance between pads and signal lines.

With the ![]() ![]() Circad will fill the layer you select in the "Target Layer" field, using the "Source Layer" field (multiple selection it's possible) as obstacle layers to avoid. Usually, you need to select all the signal layer and the "Pad Master" layer. Then, using the Flood Fill option, you'll obtain the first two examples. | ![]() |
![]() | Using the Hatch Fill option it's possibile to make a special conductive plane
with net crosslinked lines. The pcbs beside was created with, respectively,
the values 2, 20 and 40 for the left one, and 20, 20 and 20 for the right one. To remove the plane use ![]() | ![]() |

Using the Hatch Fill option, but selecting the value 1.000 in the "Crosshatch Grid"
field you can make a plane that contains the contour lines of pads and signal lines.
