Sometimes Pathfinder models include stair access for occupants which are modeled without any of the user-defined stairs tools.

Targets are an excellent choice for modeling seating for entertainment venues such as stadiums, auditoriums, or theaters as well as waiting lobbies for medical, commercial, or transit locations. Read More...
