SKETCHING

Introduction:

As instrument drawing becomes less prevalent in industry, the ability to create accurate technical sketches becomes more important. The curriculum team feels that it is critical for students to be able to communicate technical information through different types of sketches. This unit will cover the purpose of sketching, materials needed for sketching, techniques for sketching, importance of proportions, the types of sketches, and differences between isometric, oblique and perspective sketches.

​

Objectives

3.01 Apply Rough sketching 

3.02 Apply 2D sketching – Single and Multi-view. 

3.03 Apply 3D sketching – Pictorials (isometric, oblique)
