I'm currently using Slabs to show exterior site-work such as steps, patios, etc. as well as for the model base itself. On my demolition plan, I want to show some of the steps with dashed edges. The problem I'm having is that when two adjacent slabs are viewed in plan, their edges overlap. This results in a solid line in plan, even if both slab edge pens are set to dashed, because the dashes do not necessarily occur in the same place.

Is it possible to set ArchiCad to display only the slab edge line of the upper slab, so that this overlap does not occur? Is there another way of fixing this problem without resorting to 2D fixes?

Can you hide one of the slabs? Some people have also had luck with making one of the slab's lines white. I tend to do 80% of my dashed lines with 2D for ease and control (and because some of my coworkers want to see dashed lines meet perfectly at corners).

Check the attached image. It explains how to achieve this.

The line type pattern of polygons is drawn starting from their start point. The below trick works because we start the polygon for both Slabs at the same point and we are drawing them in the same direction.
If you create a Polygon using SPACE-click, the beginning point of the polygon and its direction is not under your control. This is why you should draw it manually in such a case.

That's awesome. Is there anyway to reverse the direction or alter the beginning point of the slab once it's drawn (similar to some of the modify wall commands)?

Not that I know of.
Probably could be done with some API command.

That's great if you only have 2 slabs or roofs. Unfortunately that is not always the case, especially with hip roofs.
