Selecting the rebar library from the Libraries menu, or its respective icon, will display the Rebar Library screen. This command allows you to manage and define the different rebar types used in the pier structure.

This option allows you to access and manage the rebars in your library (rebarLib.rlb). You can either modify the existing rebar definition or simply add new definition in the list.

Click Save to save the changes to the existing library (overriding the existing data). To save under a new filename, click Save As. Input a new name in the File name field and click Save.
