Sketching How to sketch design

Explanatory Drawings: Exploded Views & Instructional Drawings

2. SIMPLIFYING SHAPE

3. Simplifying Shape
• All shape can be generated from a combination of
a basic block shape;

4. • Details will give drawings a more vivid and
realistic appearance

5. • Guideline used to construct a shape will also be
helpful to the reader of your drawing, as they
provide extra visual information about shape.

6. Axonometric Projection

7. Elementary shapes and shading
the rendering approach

8. Line Weight
• Line on the shaded side (in this case, on the
right hand side) and underneath are made
heavier

9. Shading
• Usually, a shadow cast on the floor is drawn
darker than its casting on a wall.
– Use different tone value and its relative – use one
of the darkest tones in a drawing

10. Light Direction & Cast Shadow
• The light direction is chosen to create the
appropriate contrast and size of shadows;

11. Ray Light
• Lamplight creates shadows that differ in
shape, depending on the position of the light
source

12. Shading
• A shade surface appears darker if it is angled move
away from the light source, so it creates difference
shade of color on each of its visible sides.

14. Ambient Light
Due to ambient light, Cast
shadow fade out as they
get further

15. Cylinders, Spheres, and Cones
• Casting shadow start from the central axis

16. EXPLANATORY DRAWING

17. Exploded Views
• It reveal the relationship
between separate interior and
exterior parts.
• Consider balancing distance
between parts in order to
coherence the drawing

18. Instructional Drawing
• At the start up project, the complex situation was
analyzed and mapped in numerous drawings to
reveal the situation in smaller design.
• It help the client and designer get a grip on the
enormous complexity.
