Accessible Space

This is the space within a model through which Entities can move: the walkable areas within a venue, station, building, stadium, etc. It is generated automatically by LEGION Model Builder when a LEGION Model File (‘lgm’) is exported as an LEGION Simulator File (‘ora’).

To generate accessible space , your model must contain at least one origin object and one target object (the simplest possible model in LEGION Model Builder would be one that contains a Populated Zone and an Exit) and be free of errors.

Accessible space is the area within which LEGION Model Builder calculates Auto-navigation and creates Focal Drift Zones when required. Any area of enclosed CAD in a model that does not include an origin or target object will be ignored by LEGION Model Builder when the model is exported.

Note: Auto-navigation automatically works out the shortest routes for Entities to follow on their journeys through a model. It can handle discontinuous accessible space, which means it can guide Entities to intermediate targets and Final Destinations that exist on different levels. It can also include or exclude small or free-standing objects from its calculations; see Checking for Free-standing Objects .

In the model of a station pictured here, the accessible space for each level is shaded in grey. You can view your model's accessible space at any time.
