Technical Illustrations & Instructions
Interactive manuals, assembly instructions, maintenance guides and service documentation. Technical illustrations and exploded diagrams that make complex products easy to understand — a niche with low competition and high demand.
Why technical illustrations matter
Text-only manuals are read by almost no one. Photographic instructions are often unclear, hard to localise and expensive to update. Technical illustrations solve both problems — they are clear, language-independent and easy to maintain when the product changes.
For manufacturers, good technical documentation reduces support costs, warranty claims and return rates. For customers, it means confidence that they can assemble, install and maintain the product without frustration. The cost of producing good illustrations is recovered many times over in reduced support burden.
What we produce
Interactive manuals
Web-based manuals that combine 3D models, step-by-step instructions and interactive controls. Users can rotate the model, zoom in on details, click on parts to see names and part numbers, and step through assembly sequences at their own pace. Interactive manuals run in any modern browser — no app install required.
Assembly instructions
Clear, numbered assembly sequences — the kind that make flat-pack furniture and modular products a pleasure to build instead of a puzzle. We produce both static illustrated instructions (for print and PDF) and interactive web versions. Each step shows exactly which parts are needed, which fasteners go where and in what order to proceed.
Maintenance guides
Scheduled maintenance, inspection procedures and troubleshooting flows. Maintenance guides show technicians exactly what to check, how to access internal components and when to replace parts. We can produce both operator-level and service-engineer-level documentation from the same 3D model.
Service documentation
Complete service documentation packages for products that require professional maintenance. Exploded diagrams, part lists, torque specifications, wiring diagrams and step-by-step service procedures. We deliver as PDF, interactive web or both — and we can integrate with your existing parts ordering system.
Technical illustrations
Static 2D technical illustrations in the classic isometric and exploded-view style. Clean line art, callouts, part numbers and dimension lines. Suitable for print manuals, packaging, marketing materials and regulatory submissions. We deliver as vector (SVG, EPS, PDF) or high-resolution raster.
Exploded diagrams
Exploded views that show every component separated and aligned along its assembly axis. Exploded diagrams are the single most powerful technical illustration for communicating product structure. They work in print, in PDF, on packaging and as interactive web experiences.
From 3D model to documentation
Every technical illustration and interactive manual we produce starts from a 3D model — either one we build from your CAD files or an existing asset. This means your documentation is always accurate, always up-to-date and always consistent with your product renders and animations. When the product changes, we update the model and regenerate the illustrations — no redrawing from scratch.
This is the key advantage of a 3D-based documentation workflow over traditional 2D illustration: a single source of truth that feeds renders, animations, configurators and documentation alike.
Delivery formats
- Interactive web — HTML5 + Three.js, runs in any browser, no install
- PDF — print-ready, searchable, with bookmarks and hyperlinks
- SVG / EPS — vector illustrations for print and packaging
- PNG / JPEG — high-resolution raster for web and print
- Video — animated assembly sequences as MP4 or WebM
Why 3DINK for technical documentation
We understand manufacturing. We know what a parting line is, why fillet radii matter, how a countersink screw differs from a counterbore. Our illustrations show products the way they actually are — not the way a generic illustration tool approximates them. This accuracy matters when the documentation is used for assembly, service or regulatory compliance.
We also produce the renders, animations and configurators — so your documentation, marketing and sales materials all come from the same 3D model. One model, many outputs, perfect consistency.
Industries we document for
- Furniture — flat-pack assembly, modular systems, care guides
- Construction — window/door installation, façade systems, hardware
- Industrial & manufacturing — machine setup, maintenance, service manuals
- Medical devices — operation, sterilisation, maintenance procedures
- Consumer products — setup guides, usage instructions, troubleshooting

- Marine — rigging, safety, maintenance procedures
Our documentation process
- Discovery — we review your product, audience and existing documentation
- CAD review — analyse source files and plan illustration views
- Illustration — produce line art, exploded views and callouts
- Client review — you check accuracy and request changes
- Layout — we lay out pages, steps and part lists
- Delivery — PDF, SVG, interactive web or all three
FAQ — technical illustrations
How much do technical illustrations cost?
A single exploded view or isometric illustration starts from €120–300. A full assembly instruction set (8–16 steps) ranges from €600–1800. Interactive web manuals typically start from €2000 depending on complexity. Fixed-price quotes provided before starting.
How long does documentation take?
Single illustrations are delivered in 2–4 business days. Full instruction sets take 1–2 weeks. Interactive web manuals typically take 2–4 weeks depending on the number of steps and integration requirements.
Can you update illustrations when the product changes?
Yes. Because every illustration comes from a 3D model, we can update the model and regenerate the illustrations quickly — typically 1–2 days for a minor product revision. This is far faster than redrawing 2D illustrations from scratch.
Do you produce print-ready PDFs?
Yes. We deliver print-ready PDFs with proper bleed, CMYK colour, embedded fonts and bookmarks. We can also produce press-ready vector files (SVG, EPS, PDF) for your existing print workflow.
Can the interactive manual be embedded on our website?
Yes. Interactive manuals are built with HTML5 and Three.js, so they can be embedded on any website via an iframe or a JavaScript snippet. No app install required — works on desktop, tablet and mobile.
Can you integrate with our parts ordering system?
Yes. We can link part numbers in the interactive manual to your e-commerce or ERP system, so customers can order replacement parts directly from the documentation. This reduces support calls and drives parts revenue.
