Technical Pencil Drawing

Depicts subjects as technical graphite drawings with mechanical‑pencil precision, consistent line‑weight hierarchy, clean geometry, subtle cross‑hatching, Bristol texture, grayscale tones, upper‑left lighting, and smudge‑free finish.

Prompt Content

Technical pencil drawing of Subject, rendered with precise, structured graphite lines and measured shading. Use mechanical pencil look (0.3-0.5 mm), clean edges, accurate geometry, and a consistent line‑weight hierarchy (construction light, contours medium, key edges bold). Complexity level of detail. Viewpoint framing; balanced layout with generous margins, clear focal points, portrait or landscape as suits the subject. Smooth bristol paper texture, grayscale palette from soft midtones to deep graphite accents; subtle cross‑hatching and controlled gradients for form; crisp highlights lifted with eraser. Neutral studio lighting from upper-left for legible volumes and cast shadows. Emphasize clarity, proportion, alignment, and tidy technical ticks or labels where helpful. Sharp, smudge‑free finish, high micro‑detail with a calm, ordered composition.

Variables

Subject: Primary subject to depict and its key features or function; Example: cutaway of a mechanical wristwatch movement
Complexity: Desired level and type of detail; Example: highly intricate exploded view with labeled components
Viewpoint: Perspective and framing of the drawing; Example: orthographic front elevation with a 3/4 perspective inset
