Size dimensions can often restrict a feature more than is needed. When the shape or form of a feature is more important than its size, a geometric dimension and tolerance is typically used.
By the end of this course, you will be able to
- Define maximum and least material conditions
- List the five geometric characteristic categories
- Identify geometric characteristic symbols
- Define a datum and datum feature
- Describe, identify, and interpret dimensions for angular features
- Identify the sections of a feature control frame
- Describe where datum feature symbols are located on an engineering drawing
