A 3D sketch drawn true size in its height and width, but foreshortened in its depth.
1) Place the object so that the view with the most detail is parallel to the picture plane, especially if the view consists of arcs and circles. 2) Place the object so that the longest dimension runs horizontally across the sheet. 3) In some cases the above two will conflict, and when this is so, rule #1 has preference as the advantage gained by having the irregular face without distortion is greater than gained by observing rule #2. 4) Decisions about viewing an object in oblique projection should aim to show the object so that its shape is most clearly presented and is conducive to showing its dimensions.
One's a triangle.
Yes, there can be oblique lines in a triangle. However, there can only be oblique lines in a triangle if the triangle is considered to be a 'right' triangle.
With high oblique photographs, you cannot see what is known as "dead ground" (parts of the area that are behind things like buildings and hills) And with low oblique photographs, you cannot see the horizon properly.
Isometric, orthographic and oblique drawings.
One remaining drawing conventions is Oblique drawing - In this convention the angles used are 45 degrees and 90 degrees. The only difference between the two named styles is in the scale of the dimension going away from the viewer. This first example is Cavalier Oblique and shows the full scale (1:1) in the axis Cabinet Oblique' In Cabinet oblique the scale (depth) is halved whilst in Cavalier oblique the depth scale is the same as in the X and Y directions.

Oblique lines:
The artist chose to paint the scene from an oblique angle, capturing the unique perspective of the city skyline.
Oblique means at an angle.
Slanting. A slash (/) is oblique
oblique rectangular
Oblique means slanted or at an angle.
High oblique includes the horizon and low does not.
internal oblique
A Little Oblique was created in 2004.
