Walls are objects, which pedestrians and transporters moving in free space navigation mode cannot cross. They define walls and obstacles present in the simulated space.
Use these three markup shapes to draw walls on top of your drawing:
Wall - use it to draw walls of complex forms (e.g. the exterior wall).
Rectangular Wall - use it to draw rectangular areas non-accessible by pedestrians (e.g. service rooms, offices, etc.).
Circular Wall - use it to draw circular obstacles inside the simulated area (e.g. columns, pools, fountains, etc.).
Use Wall when your area has complex form. If your area is rectangular, or circular, use Rectangular wall, or Circular wall instead.
They are part of a level, which means that one wall cannot be used by multiple levels.
