Which projection type is commonly used in European drawings?

• A. Isometric projection
• B. First angle projection
• C. Third angle projection
• D. Dimetric projection

Answer: (B)

First angle projection is the standard used in European drawings. In this method the object sits between you and the projection plane, so when the views are laid out, they appear on the opposite sides of the front view: the top view goes below the front view and the right-side view appears on the left. This convention comes from ISO standards and is traditional in Europe, helping keep drawings consistent across documents. The other options describe methods that aren’t the typical orthographic convention for European technical drawings: isometric is a 3D pictorial view, and dimetric is another type of axonometric projection.
