The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: None


This command is used to convert existing Keepout objects back to their primitive design objects. A Keepout in PCB design is a user defined area or perimeter placed in the layout that copper objects cannot intersect. Typically included to control the area used by automated copper placement actions, such as polygon pours and interactive routing, a Keepout also represents an invalid location when manually placing copper objects. Placed Keepout objects can be configured to specify which type objects they apply to, such as tracks, copper areas, vias and pads, which significantly enhances the flexibility and effectiveness of Keepouts.

For more information on Keepouts, see Object Specific Keepouts.


This command is accessed from the PCB Editor by choosing the Tools » Convert » Convert Selected Keepouts to Primitives command from the main menus.


First, ensure that the keepout objects that you wish to convert are selected within the design workspace.

After launching the command, the selected keepouts will be converted back to their corresponding primitives.


  1. Primitive objects can be converted (back) to their equivalent Keepout objects using the Tools » Convert » Convert Selected Primitive to Keepouts command.
