The following are the relations between the lines in isometric projection: ItвЂ™s a pictorial orthographic projection of an object where a transparent cube containing the object is tilted before one of those solid diagonals of the cube becomes perpendicular to the vertical plane along with the three axes are equally inclined to this vertical plane. Thus, in an isometric drawing of a cube, the three visible faces appear as equilateral parallelograms that is, while all of the parallel edges of the cube are projected as parallel lines, the horizontal edges are drawn at an angle (usually 30В°) from the normal horizontal axes, and the vertical edges, which are parallel to the principal axes, appear in their true proportions. In making an orthographic projection, any point in the object is mapped onto the drawing by dropping a perpendicular from that point to the plane of the drawing.Д®ngineering Choice | The biggest engineering BlogsДЄn isometric projection results if the plane is oriented so that it makes equal angles (hence вЂњisometric,вЂќ or вЂњequal measureвЂќ) with the three principal planes of the object. The isometric is one class of orthographic projections. The technique is intended to combine the illusion of depth, as in a perspective rendering, with the undistorted presentation of the objectвЂ™s principal dimensions-that is, those parallel to a chosen set of three mutually perpendicular coordinate axes. Isometric drawing, also called isometric projection, method of graphic representation of three-dimensional objects, used by engineers, technical illustrators, and, occasionally, architects. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees. Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. We tend to call every non-perspective 3-dimensional drawing вЂњisometric.вЂќ What is Isometric Projection? Figure 5.17A An example of the use of isometric drawings in architecture and engineering (source: North American Steel Framing Alliance).The term вЂњisometricвЂќ is one of the most misapplied words in the design industry. In much of Europe, an axonometric uses a 45-degree angle as opposed to the 30/60-degree angles used in isometric drawing.

Figure 5.17A and B shows two examples of isometric drawings in an architectural context. An isometric drawing can be easily constructed by using a 30-60-90-degree triangle and T-square or with CAD programming. Isometric projection, like orthographic projection. Isometric drawing is a method of visually representing three-dimensional objects in two dimensions, in which the three coordinate axes appear equally foreshortened and the angles between any two of them are 120 degrees. An isometric drawing is one form of pictorial drawing. The isometric drawing is most commonly used in its true form giving 'equal measure' and foreshortened views of three sides of the object. One of the advantages of isometric perspective in engineering drawings is that 60-degree angles are easy to construct using only a compass and straightedge. The term 'isometric' is derived from the Greek for 'equal measure,' reflecting that the scale along each axis of the projection is the same, which is not true of some other forms of graphical projection.
