Architectural Working Drawings — A floor plan is a horizontal section cut through the building at a conventional height (often around window sill level), shown as a “bird’s-eye” view looking down to reveal room layout, wall thicknesses, openings, and fixtures.

Introduction / Context:
The floor plan is the foundational drawing for architectural coordination. It communicates spatial organization, dimensions, and relationships among walls, doors, windows, stairs, and fixed equipment. Calling it a bird’s-eye view is appropriate because it is presented as if the roof were removed and the observer looked straight down at a cut plane.

Given Data / Assumptions:

• Orthographic projection, not perspective.
• Cut plane typically at a consistent height to intersect doors and windows.
• Symbols and lineweights distinguish cut elements from items seen beyond.

Concept / Approach:
The plan is actually a horizontal section: the model is conceptually sliced at a fixed height, elements intersected by the cut are emphasized, and elements below are shown in lighter line or symbols. This method yields clarity about wall thicknesses, door swings, stair runs, and plumbing fixture positions that a pure top view would not convey.

Step-by-Step Solution:
1) Establish the cut plane elevation (e.g., around 1 m to 1.2 m above finished floor).2) Draw all elements intersected by the cut with bold lineweights.3) Add items seen below (cabinets, fixtures, floor patterns) with lighter lines and symbols.4) Dimension, tag, and annotate rooms, doors, and windows for coordination.

Verification / Alternative check:
Check door swings and window locations against elevations; they should align with the plan’s tags and dimensions, confirming that the bird’s-eye horizontal section communicates the building accurately.

Why Other Options Are Wrong:
A floor plan is not a vertical section; it is not limited to furniture; it is not a street-level perspective—those are distinct drawing types (sections, interior layouts, perspectives).

Common Pitfalls:
Inconsistent cut plane heights between floors; missing stair up/down arrows; misaligned tags between plan, elevations, and schedules.
