Final answer:
The most often used angle in an oblique drawing is 45 degrees.
Step-by-step explanation:
The most often used angle in an oblique drawing is 45 degrees.
In oblique drawing, the object is represented with a combination of orthographic and isometric projections to convey a three-dimensional view. The most commonly used angle in oblique drawing is 45 degrees, which provides a balanced representation of the object's dimensions and is easy to construct.
Using a 45-degree angle in an oblique drawing allows for clear and accurate depiction of the object's height, width, and depth.
