Isometric projection of Cylinder Sample Problem: Draw the Isometric projection of Cylinder of base 50 mm diameter and 70 mm height when it rests with its base on HP. In isometric projection, the most commonly used form of axonometric projection in engineering drawing, the direction of viewing is such that the three axes of space appear equally foreshortened, and there is a common angle of 120° between them. The isometric projection is one class of orthographic projections and if the plane is oriented an isometric projection results so that it makes equal angles. All projections of a sphere on a plane necessarily distort the surface in some way and to some extent. This effect is usually achieved by using Vanish Points.
