Match the projection with its treatment of the three axes.

1. Isometric   2. Dimetric   3. Trimetric

P. Two axes equally inclined   Q. All three equally inclined   R. All three unequally inclined

  • A.1-Q, 2-R, 3-P
  • B.1-R, 2-P, 3-Q
  • C.1-Q, 2-P, 3-R
  • D.1-P, 2-Q, 3-R

Answer: C

The number of equal inclinations decides how many separate scales the drawing needs, which is one for isometric, two for dimetric and three for trimetric. It is the reason isometric dominates practice despite the other two giving a more natural appearance.
