Sample practice questions
Easy
1. At what angle are the three isometric axes drawn to each other from a common origin point?
120 degrees
90 degrees
60 degrees
45 degrees
Answer: 120 degrees — The three isometric axes are drawn at 120 degrees to each other from a common origin point.
Easy
2. What is an isometric line?
A line on the object that runs parallel to one of the three isometric axes
Any line drawn using a compass
A line that always represents hidden detail
A curved line only
Answer: A line on the object that runs parallel to one of the three isometric axes — An isometric line runs parallel to one of the three isometric axes, and can be measured directly at its true length along that axis direction.
Medium
3. Name the set square, used together with a T-square, that constructs the isometric axes at 30 degrees above the horizontal.
Answer: 30/60-degree set square — A 30/60-degree set square is used against a T-square to construct the isometric axes accurately, with two axes drawn at 30 degrees above the horizontal.
