Service introduction
About our technical illustration service
Technical illustrations help people build, use and repair things correctly.
We work from CAD files, photos or samples to create clean line drawings or rendered illustrations with callouts that match your documentation.
Manuals and documentation
Technical illustration for manuals, patents and parts catalogues
A technical illustration usually has to do something a photograph cannot: show a part that is hidden, or a sequence that happens inside a housing.
We draw exploded views, cutaways, assembly sequences and schematic diagrams from your CAD data, drawings or sample parts. Line weights follow a fixed hierarchy so structure, hidden detail and callouts stay distinguishable at any print size. Part numbering and callout keys are matched to your existing parts list rather than renumbered.
- Exploded views, cutaways and assembly sequences
- Fixed line weight hierarchy across a whole manual
- Callouts keyed to your existing part numbering
The authors and teams we build this for include manufacturers and technical documentation teams in the United States, Germany, the UAE, Saudi Arabia and India. Send us your project details and we will reply with questions, an approach and a quote before any work starts.
