Menu: Tools --> Library Editor

Library symbols are created in two stages:

First the attributes are set and then the schematic is drawn

see Library part Attributes and

see Library part schematics.

For existing symbols either the schematic or attributes can be edited using the following controls from the Library editor:

	Edit library symbol attributes.
	Edit library symbol schematic.

Notes

After editing the attributes the library part schematic editor is displayed.  This is necessary to allow positioning of any new (or detection of deleted) attributes.
