Scale, Dimensioning, and Sketching Test

The main purpose of a technical drawing is to:

• Create artistic designs

• Provide construction instructions

• Show off drawing skills

• Calculate costs

A scale of 1:4 means:

• The drawing is 4 times bigger than real life

• The drawing is 1/4 the size of real life

• The drawing uses 4 different scales

• The drawing needs 4 views

Extension lines in dimensioning:

• Show arrows only

• Extend from the object being measured

• Connect dimension lines

• Mark the scale

The best type of dimensioning to avoid errors in manufacturing is:

• Chain dimensioning

• Parallel dimensioning

• Baseline dimensioning

• Angular dimensioning

Thumbnail sketches are:

• Highly detailed drawings

• Quick rough drawings

• Final presentation drawings

• Technical blueprints
