Certain situations require you to combine two or more Spatial Objects in order to model particular elements of a site, like gatelines or platforms or check-in desks. LEGION Model Builder enables you to place and configure the required objects and then to combine them into one by grouping them together. This technique is similar to that used with Queue Groups (see Queue Groups ).

Group Objects can be edited, copied, pasted, moved, scaled and rotated just like other singular objects.

The following example deals with three objects that are commonly used together to model an automated gateline: Focal Node, Delay Point and Drift Zone.

To group objects:

1. Draw the individual objects and set their parameters as required.
2. Select the objects in the Object Directory, right-click on one of them and select Create Group.

   Type Group into the Command Bar, select the objects in the workspace, and press Enter.

   The ‘Edit Group Object’ dialog is displayed, featuring your chosen objects in the ‘Selected’ pane and other available objects in the ‘Available pane’.

   Note: Objects that already belong to a group will not appear in the ‘Available’ pane.
3. Enter a meaningful name for the group in the ‘Name’ box.
4. If you wish to add or remove objects from this group, you can do so by moving them in or out of the ‘Selected’ pane using the selection buttons >, >>, <, <<.
5. Click OK to close the dialog.

   The new object is created and added to the ‘Groups’ folder in the Object Directory. The group can be expanded to reveal its constituent objects. The constituent objects will not be listed individually as long as they are part of a group.

   
   Tip: You can also drag and drop objects belonging to the Object Directory into or out of an existing group.
