Technical Drawing: Understanding Orthographic Projection

Orthographic projection is a way of drawing three-dimensional objects on flat paper using multiple views. Think of it like taking photographs of an object from different angles—front, top, and side—then arranging these views on your drawing sheet in a standard pattern.

Imagine drawing a simple wooden stool used in Nigerian homes. Instead of trying to show it in 3D perspective, you'd draw its front view (showing height and width), top view (showing length and width), and side view (showing depth and height). These views don't overlap; they're arranged according to strict rules so anyone reading your drawing understands the exact shape and size.

This method is critical in engineering, architecture, and manufacturing because it gives precise measurements. Every dimension can be clearly marked, leaving no room for confusion or mistakes during construction.

💡 Exam tip: Always remember that in first angle projection, the top view goes below the front view, while in third angle projection, the top view goes above—practice both methods to avoid losing marks.
