Planometric Projection

In planometric projection we take a top-down view on an object, and draw the 3d view. Along with isometric and oblique, planometric is considered to be an axonometric projection, because it employs parallel line projections. In planometric view, we use the 30/60 degrees angles (trimetric) on each side. This produces a 90 degree internal angle, and there is no forshorteneing applied to this projection. Circles in planometric view are drawn using the compass when these feature in the plan, and this makes the process faster. Planometric cylinders are also widely used in 3d piecharts.
