Artistic drawing vs. Technical drawing
What’s the difference?
Multiview vs. Isometric
Cavalier vs. Cabinet oblique
Perspective vs. Oblique
Drawing Conventions: commonly accepted practices, rules, or methods (e.g., dashed line for hidden feature)
Standards: set of rules that govern how technical drawings are represented (e.g., ANSI standards)
The use of drafting tools
Remember that Accuracy, Neatness, and Speed count in technical drawing
ACAD ISO series lines are very large.
For this class, use standard line types starting from BORDER to PHANTOM lines.
Refer to the Chapter 1 Supplement for other types of scales.
