Oblique Drawing
front graphical projection with depth shown usually 30 or 45 degrees back. Appears distorted.
An oblique drawing is a type of 2D drawing that is often used in technical or engineering fields. It is a method of illustrating three-dimensional objects by projecting them onto a flat surface at an oblique angle. The result is a drawing that shows the object from multiple angles with visible depth, but is still easy to read and understand.
There are two main types of oblique drawings: cavalier and cabinet. In a cavalier oblique drawing, the height, width, and depth of the object are all represented at full scale. This means that the depth of the object is shown in a 1:1 ratio with the other dimensions, resulting in a slightly distorted appearance. In a cabinet oblique drawing, the depth of the object is reduced to 0.5 or 0.75 of its actual size, resulting in a more accurate representation of the object’s proportions.
To create an oblique drawing, you will need to choose an appropriate angle of projection and create a grid or guideline system to help ensure that your dimensions are accurate. It is also important to use consistent line weights and shading to make your drawing clear and easy to understand.
Overall, oblique drawings can be a useful tool for showing the details and dimensions of complex objects. With practice and attention to detail, anyone can create a clear and accurate oblique drawing.
