Catalogues are places where you can store, reuse and share the following objects:

• Spatial Objects
• Model Builder data objects (Entity Types, Supply Types, Arrival Profiles, Event Profiles, Delay Profiles, Availability Profiles, Speed Profiles, Exit Profiles, Entity Colour Schemes and Value Ranges).
• Analysis data objects (Map definitions, Analysis definitions, Thresholds, and Entity Colour Schemes)

There is a default catalogue (DefaultCatalogue.lgd), into which you can choose to save all your objects, but you can also create as many catalogues as you require on local and shared drives. After you have 'registered' them using Tools > Options > Catalogue Management, they are available to use from your installation of LEGION Model Builder.

Once you have saved objects to your catalogue(s), you can reuse them in other lgm or ana files. You can also import and export the contents of catalogues. All of this can be done using the Object Store.
