Course: Technical Drawing and Design (21101-36) > Section: Exploring Technical Drawing Foundations

Application of mathematical calculations involving practical geometry may include

- scaling drawings
- converting unit systems
- using proportions and ratios
- solving for area
- solving for circumference
- calculating even-centering spacing for multi-view drawings.

Process/Skill Questions:

- How is the radius of a circle different from the diameter?
- How is the true length of an inclined plane in an orthographic projection determined?
- What functions and commands can be used in CAD software to simplify geometric formulas?
- Where can one locate the information needed to perform the calculations?
