How to Create Power Planes, for Example for GND?
To fill areas on the board with copper you have to use the POLYGON command and draw the outlines of the area to be filled. The polygon’s name determins the signal that should be connected with. After closing the contour you have to name the polygon with the NAME command. Therefore click onto the polygon’s contour and type in the signal name. RATSNEST calculates the filling of the polygon and displays it on the screen. The polygon follows the settings of the Design Rules and the values given for Net classes. The polygon area consists of single lines that are drawn with a certain width which should not be set too fine (and never be 0). The finer it is, the more the polygon will branch out on the board, but keep in mind that it will cause larger and larger amounts of manufacturing data when processing the drawing with the CAM Processor. Typically you should keep the polygon width in the same range as your other wires. So choose a reasonable value for your copper area. Another important pa
