Thank you for help


Sorry for my bad English.........and if I was unpolite

Physical surfaces (or objects) need to be named with a number at the start
i.e.
1BUKOTERGREEN_01
7GRAVELBED2_24

With no number at the start of the object name, AC doesn't see the object as 'physical' and the car will fall through it.
