MEP spaces are not visible in the section view

Problem

MEP spaces that are present in the floor plan view are not visible in the section view.

Possible cause: Starting point for detection of the MEP space

When detecting MEP spaces, the program searches for a room bounding component on the vertical axis from a given reference point. For example, if you defined the room from the top of its first floor layer and then constructed additional layers of floor on top of it, the MEP could cannot extend beyond the top layer because it respresents a room boundary. The volume of the room is calculated as zero accordingly.

Solution

You can determine the height at which Revit begins the search for vertically space-limiting components via the computation height of the respective level. Set the calculation height to at least the height of the top edge of the finished floor so that the whole room can be detected.
Tip: Alternatively, you can define the MEP space again from the top of the finished floor or use an auxiliary plane on the top of the finished floor.
