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. Also referred to as copper pours, polygon pours are similar to a region except that they can fill irregularly shaped areas of a board as they automatically pour around existing objects, 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, using either Region objects or a combination of Track and Arc objects. SummaryĪ polygon pour is a group design object that is made up of simpler primitive objects. Hiding and Restoring Polygons (Shelving and Unshelving)Ī Polygon Pour (brighter red) being used to create a large GND area on a board.Remove Necks When Copper Width Less Than.Via the Polygon Pour Dialog or Properties Panel.Defining a Polygon from Selected Objects.The polygon is added to the list at the bottom of the repour order list. (The settings are clonedįrom the original polygon by default.) When you are satisfied these are set correctly, click on OK to close the Polygon Pour dialog. Selected Polygon - the Polygon Pour dialog will open in which you can change the properties of the new pour, such as name, net, layer, and other attributes.Create New Polygon from - Click to create a new polygon then choose:.Treated as a group used by the design rules for example. You will be required to provide a name for the new polygon class in the Object Class Name dialog. Create Polygon Class - click to create a polygon class for the selected polygons.This rule specifies the style of the connection from Create Polygon Connect Style Rule - click to open the Edit PCB Rule dialog to create a polygon connection style rule with a new query for the selected polygons.This rule specifies the minimum clearance between Create Clearance Rule - click to open the Edit PCB Rule dialog to create a clearance rule with a new query for the selected polygons.Auto Name - use the sub-menus to set autonaming on or off for all or selected polygons.To commit the action, click the Apply or OK button.ĭo not forget to check and resolve the violations of all polygons before submitting the PCB for manufacturing! Locking - use the sub-menus to select which polygon(s) to lock or unlock.Shelving - use the sub-menus to select which polygon(s) to shelve or unshelve. To commit the action, click the Apply or OK button.Repour - use the sub-menus to select which polygon(s) to repour: Modified Polygons, Selected Polygons, Violating Polygons, or Force Repour All Polygons.You can select one or more polygons ( Ctrl+click) and execute repours, unpouring, locking and/or ignore Violations. Once named they can be used to scope polygon rules or create Click a column heading to sort by that column. This is a list of all existing polygons in the PCB document the columns show the current state of each polygon. ACCESSĬlick Tools » Polygon Pours » Polygon Manager to access the dialog. The polygon connection style and clearance design rules, and add polygon classes for selected polygons. The Polygon Pour Manager can also be used to rename polygons, set their pour order, perform re-pouring or disable pouring on selected polygons, add/scope The Polygon Pour Manager provides a high-level view of all polygons on the PCB design.
