Descriptive Geometry

by George Young

Master the language of form with Descriptive Geometry, a practical guide to shading, shadows, and spatial reasoning.

This book explains how light, objects, and surfaces interact to create true-to-life drawings. It focuses on the foundations of shades and shadows, the geometry of how light hits surfaces, and the ways to represent those effects clearly in plan and elevation. Readers will learn the concepts of umbra, shade lines, and how shadows reveal the three‑dimensional shape of buildings and structures.

- Understand how a light source, objects, and receiving surfaces determine shade and shadow in drawings
- Learn to use projection concepts and directrices to transfer patterns and study curved and warped surfaces
- Explore practical methods for analyzing and illustrating shadows in plan, elevation, and perspective
- Work with exercises and illustrative figures to build accuracy in drafting and design

Ideal for students of architecture, engineering drawing, and design who want to improve their ability to depict form through light and shadow.
