Baseline

The baseline cache (cache0) is generated from a selection of elements in a given Multiple Database (MDB) defined in the Graphical Changes Manager (GCM). This can be a separate MDB to the current MDB and contains all the elements needed in the cache. Only elements from databases opened in the current MDB are loaded from the cache. The baseline is also used to determine the initial 3D limits of the view when it is first opened.
