A fill is a primitive design object that can be placed on any layer. As well as the standard fill that is used for design tasks such as defining a component outline, there is a second type of fill available that is referred to as a fill keepout. A fill keepout can be placed as a layer-specific keepout object or an all-layer keepout to act, for example, as a placement or routing barrier. The difference between a standard fill and a keepout fill is that layer-specific keepout-type fills are not included in output generation, such as Gerber or ODB++. A keepout fill is identified by having an outline in the Keepout color.
Fill Keepouts are available for placement in both PCB and PCB Library Editors in the following ways:
After launching the command, the cursor will change to a cross-hair and you will enter fill keepout placement mode. Placement is made by performing the following sequence of actions:
Additional actions that can be performed during placement while the fill keepout is still floating on the cursor and before the first corner of the fill keepout is anchored are:
This method of editing allows you to select a placed object directly in the design space and graphically change its size, shape or location.
When a fill keepout object is selected, the following editing handles are available:
The following methods of non-graphical editing are available:
Properties page: Fill Keepout Properties
This method of editing uses the associated Keepout - Fill dialog and Properties panel to modify the properties of a Fill Keepout object.
During placement, the Keepout - Fill mode of the Properties panel can be accessed by pressing the Tab key. Once the Fill Keepout is placed, all options appear.
After placement, the Keepout - Fill dialog can be accessed by:
After placement, the Keepout - Fill mode of the Properties panel can be accessed in one of the following ways:
The Properties panel supports multiple object editing, where the property settings that are identical in all currently selected objects may be modified. When multiples of the same object type are selected manually, via the Find Similar Objects dialog or through a Filter or List panel, a Properties panel field entry that is not shown as an asterisk (
*) can be edited for all selected objects.
The List panel allows you to display design objects from one or more documents in tabular format, enabling quick inspection and modification of object attributes. Used in conjunction with appropriate filtering by using the applicable Filter panel, or the Find Similar Objects dialog, it enables the display of just those objects falling under the scope of the active filter – allowing you to target and edit multiple design objects with greater accuracy and efficiency.
