Managing boundaries of polygonal network objects

Note: You can edit the boundaries of main nodes, zones, main zones, territories, restricted traffic areas, and polygonal POIs.

Boundaries of polygonal network objects are polygons that define the boundaries and the spatial extent of network objects.

You can specify a boundary immediately when creating a network object or afterwards.

By default, boundaries consist of only one surface (Fundamentals: The surface data model in Visum). You can, however, also specify boundaries that consist of several faces (Creating new faces). Visum normalizes surfaces automatically when they are created or edited.

You can position new polygon points directly on existing polygon points or on point objects and merge them, if required. The following point objects can be used:

  • Node
  • Stops
  • Stop areas
  • Stop points
  • From and To points of edges

You can edit boundaries as follows:
