Illustration techniques are essential in 3D CAD modelling, helping to make your designs look more realistic and visually impressive. By adding details like shadows, lighting, textures, and reflections, rendering creates the appearance of real-world materials and environments. This makes your 3D models look like finished products rather than pieces. Whether you’re presenting a design to a client or showcasing your work in a project, rendering helps you just simply communicate your ideas more effectively by making your models look lifelike and professional.

Light
Light
Light is a key illustration technique used to bring a sense of realism and clarity to graphics. Whether it’s natural sunlight or artificial lighting, effective use of light helps communicate a design's shape, surface, and structure, making it more understandable and visually appealing.
Shadows
Shadows
Shadows play a crucial role in giving depth and dimension to illustrations. By showing where light is blocked, shadows help define the position, height, and shape of objects in a scene. They also reveal the direction of the light source.
Reflections
Reflections
Reflection is used in illustrations to show how shiny or smooth a surface is, such as glass, water, or polished metal. It adds realism by mimicking how light bounces off a surface and reflects nearby objects. It can also be used to suggest a material’s properties and improve visual impact, especially when showcasing products or architectural designs.
Tone
Tone
Tone refers to the use of light and dark areas in an illustration to suggest depth, form, and texture. By gradually changing the tone, from light to dark, designers can make flat drawings look three-dimensional. Tone helps viewers understand the volume and curves of an object, which is especially important when conveying complex or realistic forms.
Material
Material
Indicating material in illustrations helps show what an object is made from, whether it’s metal, plastic, glass, wood, or fabric. This is important in graphic communication because different materials have different properties, such as weight, strength, or flexibility. Visual clues like colour, texture, and reflection can help suggest the material, giving the viewer a better understanding of the object’s function and feel.
Texture
Texture
Texture adds surface detail to an illustration, showing whether something is rough, smooth, soft, hard, or patterned. It can be shown through shading, line work, or digital effects. Including texture in graphic communication makes a design more realistic and helps the viewer imagine what it would be like to touch or use the object. It also gives character and visual interest to drawings.

Shade
Shade
Shade can be applied to a model to give it depth and show the direction of light. This makes the model appear to be sitting on a surface.
Reflections
Reflections
Reflections can be added to objects to make them appear more realistic. For example, reflections make the object appear on a shiny surface.
Lighting
Lighting
Different lighting styles can be applied to models. It makes them look brighter or duller and can make them look realistic. For example, direct lights can be applied to models to ensure they look how designers want them to. This can mean applying a focal point or radial light.
Materials
Materials
Materials can be applied to models to show the client or customer what they will look like. For example, wood or plastic could be applied to a model.
Texture
Texture
Texture can also enhance the appearance of materials, helping the model look realistic.
Sited Environment
Sited Environment
When a model has been created, the designer can place the model into an environment. This allows the model to appear in realistic surroundings.
It is used to show:
It is used to show:
- Models in a realistic setting
- The model with additional features like trees, roads, cars etc.
- Gives a clearer idea of scale
- Can show different conditions like how it would look in light, dark or sunny conditions
Examples
Examples
Lighting has been added to the model to create highlights in the windows. Wooden materials have been incorporated into the building's exterior to make it look realistic.
Materials have been applied to the model to make it look realistic. Shadows have been applied to make the model look like it is sitting on a surface. The model has been placed in a sited environment to add to the realism and give a sense of scale.
Lighting has been added to make it look like the torch is on. A bump texture has been applied to make the handle look rough and more realistic.
Materials have been added to make the model look like plastic. Shadows have been applied to make the model appear on a surface. Decals have been added to the face and body. Texture has been applied to the ground to create bumps, making the floor look realistic.
