Question

There will be no change in length if the line is viewed parallel to plane on which the line is present and also if the line is rotated with respect to perpendicular planes.

(a) True

(b) False

This question was posed to me in exam.

I would like to ask this question from Projection of Line Inclined to both the Planes in section Projection of Lines of Engineering Drawing

Answer 1

The correct choice is (a) True

The explanation is: There will be no change in length if the line is viewed parallel to plane on which the line is present and also if the line is rotated with respect to perpendicular planes. If the line is rotated with respect to the same plane on which it is located then a new measure is formed.
