Functional drawings vs decorative drawings
A decorative drawing makes something look beautiful. A functional drawing shows how something works — it includes measurements, labels, arrows showing movement, and notes about materials. Engineers and product designers use functional drawings every day.
Labels and annotations
In a functional drawing, every important part is labeled with its name and function. An arrow pointing to the wheel says "wheel — allows rolling." This is called annotation. A drawing without labels is like a map without street names.
Top view, side view, front view
A 3D object looks different from different angles. Designers draw three views: the front, the side, and the top. Together, these three views give a complete picture of the object. This is called multiview drawing.
Sketching is thinking on paper
Professional designers sketch constantly — not to make perfect art, but to think through ideas. A rough sketch with labels and arrows communicates more than a beautiful drawing with no explanation. Speed and clarity matter more than artistic skill.
