The PCB Library panel

Summary

The PCB Library panel enables you to browse footprints stored in the active PCB library document and edit their properties. When a PCB Library document is active, the panel becomes populated with information pertaining to the constituent footprints of that library. The panel also offers the ability to pass on any changes made to them directly to the PCB design document.

Access

The panel is accessed from the PCB Library Editor in the following ways:

Click the Panels button at the bottom-right of the workspace then select PCB Library.
Click View » Panels » PCB Library from the main menus.

Panels can be configured to be floating in the editor space or docked to sides of the screen. If the PCB Library panel is currently in a group of panels, use the PCB Library tab located at the bottom of the panels to bring it to the front.

Library Browsing

The panel has three main sections, each offering a different scope or view of the footprints in the active PCB Library:

Footprints - a list of footprints in the active library. The number of pads and primitive objects used to define the footprint is listed for each entry.
Footprint Primitives - the primitive objects and their main properties that make up the currently selected footprint.
Other - a simplified, overall view of the currently selected footprint with the main editor view indicated by an overlay graphic.

As a footprint is selected in the panel, its constituent primitives populate the Footprint Primitives section and the footprint is displayed in the main editor workspace. Selecting a primitive object in the panel causes the corresponding object to be highlighted in the editor workspace. In this way, the PCB Library panel offers a fast and easy way to browse, view and access PCB library footprints.

Double-clicking on a Footprint entry opens the PCB Library Footprint dialog, and double-clicking on a Footprint Primitives entry will access its corresponding Properties panel - see more options in the Right-Click Menus section below.

Filtering Content

The contents of the list can be filtered, enabling you to quickly find a particular footprint within the library. This is especially useful if the library contains a large number of items. Filtering can be applied using the following methods:

Indirect Filtering

This method uses the Mask field at the top of the panel to filter the contents of the list. Masking is applied based on the entry in the field. Only those footprints in the list targeted by the scope of the entry will remain displayed.

Note that the Mask field is not case sensitive. To list all footprints again, clear (delete) the entry in the Mask field.

Use the * wild card operator for more elaborate filtering. For example, typing m* will display only footprints whose names begin with m, or as in the image below, typing *16 will display only footprints that contains 16 in the name.

Direct Filtering

This method is available for all list regions in the panel and allows you to quickly jump to an entry by directly typing within the area of the list. Masking is not applied, leaving the full content of the list visible at all times.

To use the feature to quickly find a footprint, click inside the Footprints section of the panel then type the first letter of the footprint to which you want to jumps. For example, if you wanted to quickly jump to footprint entries starting with the letter S, you would press "S" on the keyboard. The first footprint in the list starting with S will be made active, and the letter will be highlighted to indicate that filtering of the list is based upon it.

If there are multiple footprints starting with the same letter and especially if the library is particularly large, type additional letters to target the specific entry you require, for example, "SO" as shown below.

To clear the current filtering allowing you to enter a different starting letter, press Esc. Use the Backspace key to clear the previously entered filter characters in sequence.

Combination Filtering

In some situations it may be helpful to use Indirect and Direct filtering together. If, for example, you recall that the footprint you want to locate has a sub-type number of 4 and a prefix of PO, this information can be used as Indirect (Mask) and Direct entries.

Footprints Controls

Place - click to place the selected footprint.
Add - click to add a new footprint to the list. The default name will be PCBCOMPONENT_1.
Delete - click to delete the selected footprint. A dialog will open asking for confirmation before the delete occurs.
Edit - click to open the PCB Library Footprint dialog to edit the selected footprint.

Browsing Footprint Primitives

The Footprint Primitives section lists all primitive objects that constitute the footprint currently selected in the Footprints list. For each primitive entry, the following information is displayed:

Type - the type of primitive object (e.g., pad, track, arc, etc.).
Name - the specified value for the objects' designator (where one exists).
X-Size - the X dimension of the object (e.g., the width of an arc, track or fill, the X-Size value of a pad).
Y-Size - the Y dimension of the object (e.g., the height of a fill, the Y-Size value of a pad). This field will be empty for a track or arc.
Layer - the layer upon which the object resides.

As individual object primitives are selected in the panel, the matching object (track, arc, pad, etc.,) is graphically highlighted in the editor workspace.

Controlling the Display of Browsed Entries in the Workspace

Selecting an entry in either panel list region applies a filter, essentially using the entry as its scope. The visual result of the applied filtering on the document in the design editor window is determined by a series of highlighting controls located at the top of the panel.

Display functions

Mask / Dim / Normal - provides the options for visibly contrasting filtered and unfiltered objects within the design editor window. The effectiveness of masking and dimming is determined by the Highlighting Options set in the PCB Editor - Display page of the Preferences dialog.
- When Mask is selected, filtered objects will appear visible in the design editor window, with all other objects being made monochrome. When this option is applied, unfiltered objects will be unavailable for selection or editing.
- When Dim is selected, filtered objects will appear visible in the design editor window, with all other objects retaining their colors but shaded.

Select - when enabled (default), the filtered objects will be selected in the workspace.
Zoom - when enabled (default), the filtered objects will be zoomed and centered (where possible) in the design workspace.
Clear Existing - when enabled (default), an existing filter will be cleared before applying a new one. Disabling this option allows you to extend an existing filter, essentially refining the filter further by applying a new filter in addition to the existing one.

Any combination of these options can be enabled. For example, you might want to have all filtered objects zoomed, centered and selected in the design workspace as well as applying masking to take away the clutter of other design objects. Use the Clear button to clear the currently-applied filter. All objects in the design workspace will become fully visible and available for selection/editing. If you want to re-apply the filter, click the Apply button.

Using the Panel's Mini-viewer

The bottom section provides a mini-viewer for the document, with an image of the active footprint central to its window. The area currently displayed in the design editor window is denoted by white hash marks as highlighted in the following image.

Click the Magnify button at the top of the panel to provide a floating magnifying glass and zoom cursor in the design editor window. As you move these around in the workspace, the mini-viewer in the panel will contain the magnified image of the active footprint centered on the cursor. This allows you to browse the document at full size in the design editor window, while looking at zoomed detail in the mini-viewer window.

Use the Page Up and Page Down keys to increase or decrease the magnification. Right-click, click or press Esc to exit magnify mode.

Tips

Standard Ctrl+Click and Shift+Click functionality is supported for selection of multiple entries in a list.
The active footprint is that whose graphics are currently displayed in the design editor window. A footprint can be active without necessarily being selected and/or focused in the Footprints list.
Ctrl+Click over a selected entry in a list to deselect it. If the entry is the only one selected for that section, performing this action will clear the filter.
The keyboard shortcuts Up Arrow, Home, End, and Down Arrow can be used to display the previous, first, last, and next footprint, respectively.
In regions of the panel where multiple columns of data exist, the data may be sorted by any column by clicking on the header for that column. Clicking once will sort in ascending order; click again to sort by descending order.
You can change the order in which columns of data are displayed. To move a column, click on its header and drag it horizontally to the required position. A valid position is indicated by the appearance of two positional arrows.
The filtering applied when browsing design objects is permanent. If the Mask or Dim highlight method has been selected, all objects not falling under the scope of the filter will become faded (depending on settings) in the workspace and are not available for selection or editing. Clicking inside the design editor window will not clear the filter. A permanent filter must be cleared by clicking on the Clear button from within the panel.
The footprint that you paste into the active library document can originate from either a PCB design document or another PCB library document.
If multiple footprints have been copied to the clipboard from the main design in the PCB Editor, only the last footprint of the group to have been selected will be pasted into the library document.
If the same footprint is pasted into the library more than once or if more than one new footprint is added to the library without renaming, the copies are distinguished by the suffix - DUPLICATE, - DUPLICATE1, - DUPLICATE2, etc.
A PCB design document must be open before a library footprint can be placed using the Place command.
A PCB design document must be open in order to pass on changes made to footprints in the library document.
When a new PCB library document is created the panel will, by default, contain a single, blank footprint - PCBCOMPONENT_1.
Library footprints can be edited only in the source PCB library (*.PcbLib). You cannot edit the footprints in an integrated library (*.IntLib). You would have to de-compile the integrated library first then edit the required footprint(s) in the source PCB library document(s). The source can then be recompiled to produce the updated integrated library.
