Scope
The scope of this project was to convert photographic images and reference visuals of vehicle components into clean, easy-to-follow line art diagrams for installation manuals. The diagrams needed to support step-by-step instructions and reduce installation errors.
Challenges involved
- ● Photographs contained complex backgrounds and vehicle underbody details
- ● Overlapping parts made component identification difficult
- ● Limited visibility of fasteners and orientation in raw images
- ● Need to simplify visuals without losing installation-critical details
Workflow process
- 1. Reference Image Review
- ● Studied vehicle photos and assembly layouts
- ● Identified installation-critical components and fasteners
- 2. Photo to Line Art Conversion
- ● Converted images into line drawings
- ● Removed shadows, textures, and non-essential vehicle details
- ● Highlighted mounting locations, brackets, and hardware
- 3. Diagram Standardization
- ● Applied consistent line weights for outlines, internal edges, and hidden features
- ● Maintained customer-required illustration style with clarity suitable for technical manuals.
- ● Ensured diagrams remained readable at reduced print sizes
