Patent / Technical Drawing Conversion

Convert a colored product render to clean monochrome line art with reference-numbered callouts.

When to use this prompt

When preparing patent application figures or technical specification drawings from a color render.

The prompt

Convert this image into a patent-style technical drawing.

Output requirements:
- Pure monochrome line art on cream-white A3 paper.
- Strictly no color, no gradients, no shading fills.
- All lines thin, crisp, pure black technical strokes.
- Double-line rectangular border frame with numeric coordinate markers (1-8 along top and bottom edges) and alphabetic markers (A-F along left and right sides).
- Orthographic projection, primary view only.

Annotations:
- Add numeric reference callouts pointing to each component, with thin leader lines and arrowheads. Specifically:
  1 — housing
  2 — motor
  3 — battery (located underneath the motor)
  4 — magnet
  5 — opposing (facing) magnet
- Use cross-sectional hatching where appropriate to indicate solid material vs hollow space.

Preserve:
- Spatial arrangement and proportions of all components.
- Numbering must match the listed semantics.

Output should be suitable for direct submission as a patent figure.

Variations

Exploded patent view

Same patent style, but render an exploded view along the primary assembly axis with each component separated and labeled with its callout number.

Tips

  • Always specify "no color, no shading". Patent styles require strict line art.
  • List the callout-to-component map explicitly. Number-only diagrams are ambiguous.
  • Mention hatching for cross-sections. Without it the figure looks empty.
