Step 2: Engineering Curves (Important for exams)

Learn the string method for ellipse.
Memorize the difference between cycloid (point on rolling circle) and involute (point on unwinding string).
Tip: Draw each curve on grid paper twice – once by method, once by French curve.

Part 1: The Fundamentals (Chapters 1–4)

Drawing Instruments & Techniques: How to sharpen a pencil for a 0.3mm line, using mini-drafters, and maintaining line thickness.
Geometrical Constructions: Dividing a circle into 12 parts, conic sections, cycloids, and involutes. Dubey’s unique spiral construction method is a highlight.
Scales: Plain, diagonal, comparative, and vernier scales—explained with real-world map reading examples.
