Group types by library

Group by item type

Group by subtypes
|
When grouping by item types, all item types display at the top level by default. It is possible for an item type to be derived from another item type. For example you might have an item type called Valve which defines the properties common to all Valves. However, the library may contain subtypes of valve such as Gate Valve, Ball Valve, and so on. These subtypes inherit the common properties defined by the Valve Item Type but also include properties specific to that particular subtype.

|
Group related items by relationship type
|
Groups related items based on their relationship type. Items in the DGN file can be related to other items. You can navigate this hierarchy by expanding an item to see related items.
|
Off
|
|
Show hidden item types
|
If off, hides item types used by the Browser that provide no business value to the user. These should remain hidden unless you have a specific need to display them.

Show all related items as children
|
Natural Hierarchy identification is based on the EC (engineering content) relationship’s strength and direction parameters that are used to connect EC instances. This option is used to choose whether or not the tree should follow the Natural Hierarchy. If on, the tree ignores Natural Hierarchy and shows all available relationships. If off, the tree follows the Natural Hierarchy rules and shows relationships depending on the relationship’s strength and direction.
