Answer:

: a projective drawing of which the frontal lines are given in true proportions and relations and all others at suitable angles other than 90 degrees without regard to the rules of linear perspective

In the oblique sketch, circular lines that are parallel to the frontal plane of projection are drawn true size and shape. Hence circular features appear as circles and not as ellipses. This is the main advantage of the oblique sketch. The three axes of the oblique sketch are drawn horizontal, vertical, and at a receding angle that can vary from 30 to 60 degrees. The axes' proportional scales are (1:1:n) where n is a scale anywhere between ½ and 1. If n = ½, then it is a Cabinet oblique. If n = 1, then it is a Cavalier oblique.

Figure 1. In the oblique sketch, the frontal plane features are all drawn true size and shape. The direction of the receding axis can vary from 30 to 60 degrees, and the scale along that axis can vary from ½ to 1.
