The top and bottom reinforcement seem to be reversed in the graphic.

Answer

Background: Each surface has a local coordinate system in RFEM (x,y,z).

The coordinates x and y are in-plane, z runs perpendicular to the surface.

The top and bottom side of a surface is determined by the direction of the z-axis.

The direction of the local z-axis determines the bottom side of a surface. Usually, this local z-axis is orientated downwards. Depending on the defined direction of the boundary lines and the sequence in which the lines were clicked., it is also possible that the local z-axis points upwards.

It is easy to correct this. First, display the local surface coordinate system.

To do this, proceed as follows:

Go to the "Display" navigator on the left. Here, you can set all display properties in a tree-like structure.

Open the entries "Model" -> "Surfaces" and select the "Surface Axis Systems x,y,z" check box.

The bottom reinforcement is on the side of the slab, where the z-direction is positive.

To reverse the direction of the local z-axis, click the corresponding surface, and then select the "Reverse axis system" option in the context menu.
