Technical illustrations
Making visual information clear and immediately actionable
Technical illustrations are a key driver of understanding in complex industrial and technical environments.
Technical diagrams, exploded views, standardized illustrations and functional graphics make it possible to visualize a product, a procedure or an assembly without ambiguity, where text alone reaches its limits.
Why use technical illustrations?
A technical illustration allows for a quick understanding of a product or system's structure.
It allows to:
01
Make assemblies, sub-assemblies and components visible
02
Secures the execution of operations
03
Limits the risk of interpretation errors
04
Facilitates maintenance and
troubleshooting
05
Showcase high-tech products or equipment
Diagrams, exploded views and standardized illustrations
LCSI creates various types of technical illustrations depending on their intended use and medium:
Technical diagrams
Technical diagrams represent equipment operation, mechanical, electrical, or functional flows, as well as the core principles of a system. They are used to explain the overall functioning of a product, support operating or maintenance procedures, and facilitate the understanding of complex systems, especially when text alone is insufficient.
Exploded views
Exploded views allow for the clear identification of a product’s components and their relative positioning. They are widely used in spare parts catalogs (with or without hotspots), as well as in maintenance manuals and assembly/disassembly procedures. Each component is identified and referenced consistently with the associated Parts List (BOM) to ensure reliable identification and field operations.
Standardized illustrations and technical graphics
All illustrations follow sector-specific graphical codes, standards and conventions.
Pictograms, symbols, visual markers and conventions ensure fast, unambiguous interpretation, particularly in highly regulated environments.
Interactive illustrations with hotspots
Interactive illustrations with hotspots enhance technical views through clickable or hoverable zones. These zones, defined by LCSI, highlight specific parts of the illustration and simplify component identification.
They visually link a reference callout to its corresponding part, improving the readability of exploded views and streamlining the navigation of spare parts catalogs. This approach also helps reduce identification errors during maintenance or ordering processes.
Depending on the client's needs, hotspots can be applied solely to the callouts or to both the callouts and the associated parts. This flexibility improves the user experience while meeting the requirements of technical and regulated environments.
Immediate understanding of procedures
Visuals play a decisive role in technical procedures. Illustrations make it possible to visualize each step of an operation, clearly identify work areas, and pinpoint risks or critical checkpoints.
They guide the user progressively and ensure the safe execution of technical tasks, step by step.
Illustrations integrated into the documentation ecosystem
Technical illustrations are rarely produced as standalone assets.
LCSI intervenes:
-
as part of technical writing projects,
-
alongside spare parts catalog development,
-
to update existing visuals,
-
following work performed by another provider,
-
during product evolutions or technical modifications.
Updating and evolving technical illustrations
Products evolve, and illustrations must keep pace with these changes.
LCSI handles the revision of existing illustrations, updates to exploded views and diagrams, and their adaptation to new product configurations. The illustrations remain consistent with updated documentation versions, ensuring reliable, actionable, and sustainable documentation over time.
Industries and applications
Technical illustrations produced by LCSI apply to a wide range of sectors, including:
Defence
Rail industry
Industrial equipment and complex systems
Mechanical and electromechanical systems
Technical products subject to high operational constraints
