Performance requires knowledge of orthographic projection, demonstrated by developing a three-view sketch of an object using appropriate drafting conventions and symbols such as various line types, dimensioning techniques, and proper views. Performance also requires the ability to
- develop isometric sketches from orthographic views
- sketch both orthographic and isometric views of objects that would solve mechanical problems such as brackets, mounts, parts of mechanisms
- sketch objects from oral descriptions.
Process/Skill Questions:
- When might it be necessary to draw sketches?
- When developing new products or processes, what happens after a sketch is made?
