Parametric Studio 2D plan representation escalators

How do I adjust the height of the 2D plan representation of the escalator? My slab has low points and after placing the escalator the 2D representation is embedded in the slab. 

I'm creating a plan view (DV) from the level above where the escalators are placed. I've went into the parametric studio and found the escalator.paz cell but I'm unable to adjust the height of the 2D plan.
