Sections, floor plans

When looking at a floor plan or ceiling plan, the cut plane is the conventional level at which everything is cut off (eg. 1m) - though Revit's default for floor plans = 1.2m
Floor plans

You can adjust what you see in the floor plans by editing the View Range properties (under 'Extents" in view properties).

• Top offset = where you're veiwing from eg. down, in Revit's case defaults to 2.3m down
• Cut plane offset = plan cut (Revit default = 1.2m)
• Bottom offset = where your view stops (eg. ground, 0)

Ceiling plans

Remember that the view here is as if you're below looking up at a ceiling, rather than down...
Otherwise, similar principles to editing the view as for the floor plan above (providing you remember you're looking up, not down)
