Get yours products their best impact


Hello everyone! My name is Jean-Christophe Tilman, and I’m excited to introduce you to Illu3D, my project as a technical illustrator freelance. My main goal is to assist companies in explaining complex concepts through visuals, rather than words. Together, we can enhance your product communication with professional 2D or 3D technical illustrations or animations.

When do you need a technical illustrator freelance ?


Generally speaking, a technical illustrator freelance is basically a 3D modeler of an industrial product. This model is subsequently used to create a photorealistic rendering. A single model can be used in several illustrations, for example by changing the angle of view, the material or the color of certain components.

Technical illustration allows a better understanding of a commercial product. It highlights the advantages offered compared to its competitors, and thus, makes functionalities visible which are not always visible on a photography.

Sectional views, ghost views, or exploded views make it possible to reveal  components that are usually hidden by other parts, a canopy or a coating.

What are the key points of a good illustration?

Whether for an exploded view, a sectional view or a phantom view, it is essential that the illustrator understands the product to be illustrated, how it is manufactured, assembled and used.
My long experience as an industrial designer has a great advantage in this area.

The technical illustration of an industrial product must be as faithful as possible to the final product..
The difference between the illustration and a photograph of the product must be imperceptible.
Respect for dimensions must be total, materials and textures should come as close as possible to reality.


What are the steps in creating a technical illustration?

2D technical illustration of a ventilation system.

A technical illustrator freelance will first gather as much data as possible on the product to be illustrated. If possible, production files such as plans in DWG format, or even 3D files in STEP or IGES format.
Details on the product, such as production process, handling or assembly can be useful.

The second step consists in modeling the product in 3D. This step is always validated by the customer, in order to verify that the modeling conforms to the manufactured product.

Finally, the creation of the technical illustration itself, a photorealistic rendering with textures, lighting and eventual background image. In low resolution first, then in high resolution, depending on its use.
