Plan view vs elevation view compares the floor plan with the elevation. A plan view is the floor plan looked at from above, showing arrangement, room dimensions, wall thicknesses, openings, routes, fixtures and stairs. An elevation view is one face drawn flat, showing openings, materials, roof profile, proportions and visible heights, without perspective convergence. Elevation view vs plan view asks for that same floor plan vs elevation pair in the other order.

| Question | Plan | Elevation | Section |
|---|---|---|---|
| How big is this room? | Yes | No | Height only |
| What is this room next to? | Yes | No | Partially |
| How do I get from here to there? | Yes | No | Vertically only |
| How tall is the ceiling? | May carry notes | May carry levels | Vertical relationship |
| What does the street see? | No | Yes | No |
| Where does the roof drain? | Roof plan / notes | Outlets may be shown | Falls at the cut; check details |
| How thick is the wall build-up? | Thickness only | No | Yes |
| Is there a step between these rooms? | Level markers / notes | May show levels | Vertical relationship |
Three cuts through the same building
Plans, elevations and sections are all orthographic drawings: parallel projections with no perspective. Use labelled dimensions first. Before scaling an approximate distance, confirm the stated scale, original sheet size, print/PDF scaling and issue status. “Fit to page” can change the scale; do not use a scaled estimate where a dimension is missing or drawings conflict. Ask the author for clarification.
They differ in where the imaginary cut is taken and where the viewer stands.
Floor plan
A horizontal cut at a stated or conventional height, viewed from above.
Shows: arrangement, room dimensions, wall thicknesses, openings, routes, fixtures and stairs. Level and ceiling notes may also be included.
Use another view for: vertical relationships and construction details.
Conventions: cut walls use heavier lines; door arcs show swing. Dashed overhead items and stair arrows should be checked against the drawing legend.
Elevation
A flat view of a building face, without perspective convergence.
Shows: openings, materials, roof profile, proportions and visible heights.
Use another view for: interior relationships and precise recess depth. A section or detail explains a reveal better.
Conventions: named by orientation or relationship, such as south or front; check the ground line and marked levels.
Section
A vertical cut, viewed horizontally, primarily explaining heights, levels and construction.
Shows: floor and ceiling relationships, stairs, roof and wall build-ups at the cut. It can also include projected background features, explicitly described in NPS HABS guidance section 3.5.4.
Use another view for: overall floor arrangement.
Conventions: the plan marks the cut and viewing direction; line weights distinguish cut and projected construction. Check the project legend for hatching or poché.
Same assumed building, three views
The opening W1 is the same in all three teaching sketches. A–A marks the section cut and its view direction; the assumed floor, opening and roof levels agree between elevation and section. These are not scaled construction drawings. Tap each image to enlarge.
Where misunderstandings happen
Approving only the plan: also check heights, levels and roof form in section.
Treating a render as a specification: confirm any important feature on an issued drawing or in the specification.
Reading depth from an elevation: ask for the reveal section or detail.
Assuming one plan covers everything: compare every floor and roof plan for coordination.
What to ask for and when
During concept and schematic design, plans do most of the work — see how to read a house floor plan. Ask for a section as soon as heights, levels or the roof come up, which is earlier than most clients think.
Which drawings you receive, and when, is set by the appointment — see what does an architect do — and by the stage the project has reached, covered in the five stages of architectural design and the architectural design process guide.
By design development you should expect plans, elevations and sections that agree with each other. Disagreements between them at that stage are the coordination issues worth raising.

Frequently asked questions
Which drawing should I ask for first?
Plans, because arrangement drives almost everything else. But ask for a section as soon as levels, ceiling heights or roof form are being discussed — those questions cannot be resolved on a plan.
Is an elevation the same as a rendering?
No. An elevation is a measured, flat, orthographic drawing of one face, with no perspective. A rendering is a perspective image intended to convey appearance and atmosphere, and it is not dimensionally reliable.
Why are some lines on a floor plan dashed?
Dashed lines usually indicate something above the cut plane or otherwise not directly visible — overhead cabinets, a beam, a roof overhang, a mezzanine edge.
What is the difference between a section and a cross-section?
They describe the same kind of drawing. In practice "cross-section" often implies a cut across the shorter axis of the building, and "longitudinal section" a cut along the longer one, but both are simply sections taken on stated lines.
