The Show Safety Zones function enables or disables the display of the safety zone that surrounds any collision enabled object that also has a safety clearance distance defined. The safety zone appears as a transparent light blue surface, offset from the original surface by the safety distance.
An object’s safety zone is always shown in transparent orange when
another collision-enabled object touches it, regardless of the Show
Safety Zones setting. Colliding objects are always shown in transparent
red. The intersection between colliding objects is shown as a bright
yellow line, unless this feature is disabled in the Simulation»
