In architectural drafting practice: On an elevation plan, dimensions are used to indicate which of the following items for a building—finished floor elevations, roof overhangs, and roof pitch angles?

Introduction / Context:
An elevation plan is a primary architectural view that shows a building’s exterior surfaces. Beyond visual appearance, it conveys critical dimensional information needed for layout, fabrication, and code compliance. This question asks which kinds of dimensions are typically carried on elevation sheets.

Given Data / Assumptions:

• The context is a building elevation drawing used during design, permitting, or construction.
• Candidate dimension types include finished floor elevations (vertical datums), roof overhangs (horizontal projections), and roof pitch/slope angles.
• We assume standard architectural drafting conventions.

Concept / Approach:

Elevations provide vertical control (heights) and key horizontal extents that relate to structure and weather protection. Roof slope is also commonly called out as rise per run (for example, 1 in 12) or as degrees to aid framing and drainage calculations.

Step-by-Step Solution:

Verification / Alternative check:

Reviewing standard sheet sets shows elevation callouts for Finished Floor Level (FFL), parapet and ridge heights, eave overhangs, and roof pitches. These appear alongside materials and datum markers.

Why Other Options Are Wrong:

Finished floor elevations only: incomplete because roof overhangs and pitches are also standard.

Roof overhangs only: ignores essential vertical and slope data.

Roof pitch angles only: omits critical elevation datums and horizontal projections.

Common Pitfalls:

Confusing plan-view dimensions (e.g., overall building length) with elevation dimensions. Elevations emphasize heights, slopes, and projections visible from that facade.

Final Answer:

All of the above
