I have entered the structural system with the "z-axis directed upwards". Now, there are some directions misrepresented for the definition of suspender and downstand beams and the output of the required reinforcement.

Answer

The bottom reinforcement for surfaces is defined in direction of the positive local surface axis z. Accordingly, the top reinforcement is defined in direction of the negative local surface axis z. The surface axes can be switched on in the Display navigator by selecting "Model" -> "Surfaces" -> "Surface Axis Systems x,y,z". Alternatively, you can use the surface context menu. The orientation of the local z-axis of a surface can be changed by using the option "Reverse Local Axis System" in the context menu of the surface.

The bottom reinforcement for members is defined on the member side in direction of the positive local member axis z. Accordingly, the top reinforcement is defined in direction of the negative z-axis. To display the member axes, use the Display navigator where you select "Model" -> "Members" -> "Member Axis Systems x,y,z". You can also use the member context menu to check it.
