Cable tray elevation / rise

Hi,

Is there a way to automatically draw an arrow on cable tray that is between 2 different elevations (so cable tray is not horizontal but at angle)? If that arrow is not drawn it's really hard to interpret these from the drawing.

Thanks in advance.

create a slab with Pos Attribute, so you can identify
