140 Chapter 8—Device Symbol Editing

 Click the Rename button. You will be prompted for each selected item

to enter a new name. Names must be unique within a library.

Getting Information on a Symbol in a Library

You can display information on a symbol, such as the exact location of the

source library and a summary of attribute values, by right-clicking on the item in

the parts palette, then selecting the Properties command. Part information can-

not be modified in this display. To modify part attributes and other properties,

select the Edit Part command and use the symbol editor facilities to make the

desired changes.

Reordering Symbols Within a Library

Several options are available in the Library Maintenance box for reordering

symbols within a library. These options do not affect the data associated with

any symbol, they merely change the order in which they are indexed in the

library file, which affects ordering in some internal operations.

NOTE: Items displayed in the Parts palette are always sorted alphabetically, so this

procedure will not affect the displayed list.

First, to display this box, select the Lib Maintenance command, either in the

Libraries sub-menu of the File menu, or by holding the š key pressed while

clicking in the Parts palette. Two kinds of reordering operations are available:

 The Promote and Demote buttons cause the selected items in the Source Lib

to be moved up or down the list, respectively.

 The Sort button sorts the entire list alphabetically, with the numeric part of

any name treated as an integer. The adjacent arrow buttons determine the

direction of the sort.

Compacting a Library

When parts are deleted from a library, the free space in the file is not automati-

cally recovered. In most cases this is not a significant overhead. However, if a

large percentage of the parts in a library have been deleted then you may wish to

compact the file. To do this:

 Create a new, empty library which will become the target for the

Compact operation.
