If you try building a wooden birdhouse without a plan, your pieces might not fit together, wasting time and materials. That is why professional designers always start by drawing flat, precise plans before cutting anything.
These flat working plans are called 2D solutions, and they tell a builder exactly how to cut, measure, and assemble a product.
What makes a 2D drawing different from a simple artistic sketch?
What is a 2D Solution?
A 2D solution is a flat drawing that shows only two dimensions: width and height (or length and width). Unlike a 3D picture that shows depth and perspective, a 2D drawing looks straight-on at a single flat surface.

Core 2D Design Methods
Designers use orthographic projection, which means looking at an object from the front, top, and side as if you were looking directly through a pane of glass.
To make sure parts fit, drawings include dimensions (exact measurements with arrowheads) and use a scale ratio (like 1:2, meaning the drawing is drawn at half real-life size).

Choosing Graphic Methods
Designers select specific graphic methods and materials depending on the intended function of their design.
