Perspective Sketching

Perspective sketching is a useful yet complex way to draw objects in three dimensions. There are three types of perspective sketches: 1-point, 2-point, and 3-point perspective drawings. Each type provides a different method of creation and a different view of an object. Perspective sketching is an alternative to isometric sketches that show more of an organic shape, rather than the specific angles of isometric drawings.

1. What is a vanishing point?

A vanishing point is a point used to draw depth when creating perspective sketches. In a sketch, it is where each line starts from to connect to the object. Each type of sketch name is based on the number of vanishing points used.

2. Aside from the number of vanishing points, what is the difference between a one-point, two-point, and three-point perspective sketch?

The difference between each type of sketch, besides the amount of vanishing points, is the way it is viewed. In a 1-point sketch, the view is focused on the object’s front face, and seems a little awkward in proportion. A 2-point sketch focuses on two sides of the object and is also the most common. A 3-point sketch gives a bird’s eye view of the object, giving focus to two sides as well as the top.

3. How does a perspective drawing differ from an isometric drawing of the same object? When would you use a perspective view in lieu of an isometric drawing?

Perspective drawings are more realistic on the angles of an object. Isometrics don’t look too realistic at times, but they show more of the object than perspective sketches do. Isometric drawings are also a simpler way to draw an object in three dimensions. Perspective sketches would probably be used if someone would like to see what the object would look like in real life. Multiple sketches may need to be created to catch every angle and part of the object. Perspective sketches would really be used when drawing real life objects with a more organic shape, while isometric drawings would be used when drawing concrete and geometrical shapes.
