Definition
A view in a technical drawing in which the front face of the object is shown true to size and shape, and the depth (the third dimension) is shown by parallel lines drawn at an angle, usually 30 or 45 degrees, to the front face.
Plain English
A drawing of an object that shows the front straight-on, with the sides and top sloping off to one side at an angle so you can see depth.
Context Anchor
Seen in aircraft maintenance manuals, parts drawings, and repair sketches when a flat view would not show the shape clearly enough.
Derivation
From the Latin obliquus, meaning slanting or sideways. The slanted lines used to show depth give the view its name.
Why Pilots Care
Maintenance technicians read technical drawings constantly. Recognising an oblique view means knowing which face of the part is shown true-size and which dimensions are foreshortened, so measurements and shapes are interpreted correctly.
Analogy
Imagine a cardboard box sitting square on a desk in front of you. If you slide your head a little to one side so you can see the front straight-on but also catch the top and one side at a slant, that is the oblique view.
Intuition Check
Oblique does not mean unclear or approximate here. It means the object is shown from a slanted angle so its depth can be seen.
Example Sentence 1
The technician used the oblique view in the manual to identify the location of the access panel on the side of the housing.
Example Sentence 2
Check the oblique view on page 62 to see how the control cables route around the pulley cluster.
