	When primary information is drawn in elevation, the interpretation can be enhanced by an oblique projection. This is a simple method of producing two-dimensional images of three-dimensional objects. The differentiating characteristic of oblique projection is that the drawn objects are not in perspective, and so do not correspond to any actual obtainable view.

−	The isometric was the standard view until the mid-20th century. Unlike the axonometric projection, the isometric plan view is slightly distorted, using a plan grid at ~~30 degrees~~ from the horizontal in both directions. It can be used to show the nature of the design and explain construction details more clearly than an orthographic projection. It is sometimes used during concept design to help the client grasp the mass of the proposal.	+	The isometric was the standard view until the mid-20th century.
