Difficulty with visibility graphics for structural plan

[b_isufiFNCSG]

I am struggling to define the visibility graphics correctly for my structural plans so that the concrete edges (whether  defined by a beam or by a slab) are shown by a solid line and the beams by a dashed line, as indicated in the figure below. I have tried changing the linetypes in Structural Framing and Floors, but I can't reach the desired result (I get dashed lines everywhere, or different types of lines at the same place). I am sure there is a solution for this, can you guide me please?

which direction are the plan looking UP or Down ?
did you edited the View range?

Plans are looking down. I didn't edit view range but it seems just fine.

Putting your plans in 'Structural' Discipline will give the desired results above. 

If you have a Beam along the edge of the Slab, and join them - this will show as you need it.
