The Open option displays the following standard file selection dialog allowing you to choose which catalog to open.
Note: The initial default path that the Catalog Editor uses is your ...Configuration\Workspaces\WorkSpace\Standards\OpenPlant\Catalogs\Imperial\ directory. If you open a catalog from another directory, then that path will become the default the next time you attempt to create a catalog in that project. If you open a new project, the Catalog Editor will refer back to the default directory.
Select a catalog and click Open to load the catalog into the editor interface.
