Freehand Sketching



This unit on freehand sketching is perhaps one of the most important skill the students will learn in this class. It is a valuable skills in both technical and non technical work. In this one day lesson, through a series of exercises, the students will be introduced to the basic skills for sketching horizontal, vertical, and inclined lines. During this lesson the students will also learn to sketch squares, rectangles, and angles.

In additional lessons related to technical sketching circles, arcs, ellipses, and the geometric shapes will be covered.

Practice in the application of sketching to elementary single view drawings will be part of a five (5) hour lab activity to complete the initial exposure to the unit on sketching.

Sketching however should be an ongoing activity throughout the course and is an excellent activity for homework assignments. Sketching the tentative solution of multi-view problems will add to the skills of the students
