1.)Oblique sketch has a more focus on the front side of an object or the face while isometric sketch focuses on the edge of an object. 2.)Oblique sketch drawn usually using the 45-degrees angle to render the third dimensions while isometric sketch drawn using 30 degrees angles.
An oblique sketch is a type of pictorial drawing in which the object is drawn with one face parallel to the picture plane and the other faces at an angle. This creates a three-dimensional representation of the object with foreshortened dimensions. Oblique sketches are commonly used in engineering and technical drawings to provide a clear visualization of an object's form and structure.
name three basic dimensions of orthographic drawing
An isometric drawing is a schematic detailing a three-dimensional object in an abstract space that has no vanishing point. So, you can see the thickness of the object, but all sides remain parallel, unlike how objects appear in real life. In real life, the sides of an object converge as they get farther and farther from the eye. Think of a building whose sides slope into a point off in the distant horizon. These drawings are helpful in giving precise measurements, scale, placement and proportions. A good example of an isometric drawing would be the assembly instructions that come with a piece of household furniture.

An isometric is more specific
An orthographic drawing is one that uses a sort of perspective that does not portray an object the way it would look in a natural space. It shows each side of the object as flat and parallel to the "picture plane." It's not too unlike cubism. (Braque and Picasso explored drawing people and object by showing all sides at once.) This is used in order to give accurate engineering/mathematical dimensions. It is used for the fabrication of mechanical parts, furniture...
you are creating a multi demensional figure.
Isometric, Orthographic and Perspective, but perspective is not required to depict an object.
One technique used by drafters is that of multi-view drawings, which show an object from different viewpoints. Three views are common, but some simple structures only need one, while complex ones need four or more.
