INPUTS

input_image REQUIRED

filename of the input 3D rendered mechanical part image

e.g. 3d_render_of_mechanical_part.png

REQUIRED CONTEXT

  • input_image: 3D render of mechanical part

OPTIONAL CONTEXT

  • negative_prompt
  • generation settings

EXPECTED OUTPUT

Format
unknown
Constraints
  • one technical drawing sheet containing three clearly separated drawings: dimensioned orthographic views, a centered sectional view, and an undimensioned isometric reference
  • suitable for manufacturing reference

SUCCESS CRITERIA

  • Generate a mechanical engineering drawing sheet with three separate drawings
  • Include fully dimensioned orthographic views with precise measurements
  • Include a sectional view through the center axis with hatching
  • Include an isometric reference view without dimensions
  • Follow ISO mechanical drafting standard in monochrome

FAILURE MODES

  • Generating single combined or merged views
  • Adding artistic rendering, colors, shadows, or textures
  • Missing dimensions or annotations
  • Using perspective distortion or sketch style

CAVEATS

Dependencies
  • input_image '3d_render_of_mechanical_part.png'
  • Reference scale of 360 mm flange diameter
Missing context
  • Detailed description of the mechanical part's geometry (relies heavily on input_image)

IMPROVEMENT SUGGESTIONS

  • Introduce placeholders for 'input_image' and 'reference_scale' to enhance reusability, e.g., '{input_image}', '{scale_mm}'
  • Add optional fields for custom part-specific annotations or additional views

USAGE

Copy the prompt above and paste it into your AI of choice — Claude, ChatGPT, Gemini, or anywhere else you're working. Replace any placeholder sections with your own context, then ask for the output.
