• New Area Load command to automatically generate the loads on floor systems with one way decking. This command will automatically distribute the load acting on a floor to the members supporting the floor. Area loading will automatically be recomputed during analysis in the event that the geometry of the floor changed since it was first specified.

• Ability to specify Area Load graphically.
