Virtual beam

I have a problem with creation of virtual beams, please see the attached image. When I create the virtual beam in the upper and the lower slab, the direction is ok (see the virtual section local axis).

But when I want to do the same for the wall - the red selection - the axis is in a wrong direction, I want it to be in the global axis Z direction, see the second image attached. I tried to do it with the Direction Vector (0,0,1), but nothing happens when I try to add it.

Ive also attached the model.

Virtual beams can't be formed in global Z-direction. It can only be made global X-Y plane.

To obtain the results along the particular line or plane for plate, beam or solid elements, local direction force sum option can be used.
