Floor-Plan Cut and Visibility Studio
Move one horizontal cutting plane through a coordinated room section and observe how the same doors, windows, stairs, counters, and overhead elements must be represented in plan.
Intersected features
Features whose vertical range crosses the selected plane.
Ceiling level
Classroom section datum; project levels govern.
Drawing controls
Read the vertical section first
The plan is not an arbitrary top view. It is the projection produced after a horizontal cut. A feature is cut only when the plane passes through its vertical extent. Geometry above or below the plane uses the documented project convention.

Door D-1
leaf and swing shown when the opening is intersected
Window W-1
frame and glazing shown when the cut passes through the opening
Clerestory W-2
normally shown overhead or referenced when above the cut
Fixed counter
solid outline below the cut; dashed only when project conventions require
Overhead beam
overhead linework when above the cut; cut profile when intersected
