GET 102 PICTORIAL DRAWING Objective Question

Question

When is the ordinate method for drawing isometric curves primarily used?
Options
A For large, complex curves where precision is paramount.
B For small fractions of a circle, where other methods might deviate from a true ellipse.
Correct Answer
C When drawing multiple parallel curves simultaneously.
D As the primary method for all isometric circles and curves.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 22 specifies, 'However, for small fraction of a circle the ordinate method must be used, since the approximate method deviate from a true ellipse at several points on the curve.'

Hint

Consider situations where the approximate method might not be accurate enough.
