Note that each polygon has a Name, which is a system-defined name that is based on the layer and the net.Select the required net in the Connect to Net drop down.Select the polygon Fill Mode these are discussed in more detail below.
PlacementĪfter launching the command, the Polygon Pour dialog will open:ĭefine the properties of the Polygon before placing it. To place a polygon, switch to the required layer then click Home | Pour | from the main menus. You can place them directly or create them from selected primitives. Polygon Pours can only be placed in the PCB Editor. Hatched polygon pours are commonly used for ground purposes in analog designs. On a signal layer, you can place a solid polygon pour to define an area for carrying large power supply currents, or as a ground-connected area for providing electro-magnetic shielding.
A polygon pour is a group design object - that is, it is made up of simpler primitive objects, either regions, or tracks and arcs. Also referred to as copper pours, polygon pours are used to fill irregularly shaped areas of a board, automatically pouring around existing objects and connecting only to objects on the same net as the polygon pour. Polygon pours are used to create a solid or hatched (lattice) area on a PCB layer.
