The purpose of the Library editor is to define and initialize a Library.
Only the database administrator can update the Library Definition or delete a Library.
The Library instances are automatically copied to the Design Explorer view. As soon as you import entity instances into this view, the information associated with this Library is loaded into your workspace. The Library entity shows up in the current location under the Library branch. You can also create a Library in the Design Explorer view.
A Pacbase database is structured in Libraries. Libraries are hierarchically structured on a maximum of nine levels. The hierarchical structure is determined when Libraries are created and can be modified by the deletion or creation of a Library . The hierarchical level of a Library corresponds to the general nature of the information it contains. A specification is described in the connection Library of the user but also in the higher Libraries of which this Library is dependent.
Any modification in a given Library immediately affects all its dependent Libraries.
