a. ISOMETRIC PROJECTION When a solid is resting in its simple position, the front or top view, taken separately, gives an incomplete idea of the form of the object. (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.) This is best illustrated by considering isometric views of an inclined cube. Since, in isometric projection, the isometric line makes an angle of 30° with the horizontal lines, therefore, their length is not equal to the actual length, but it is only 82% of the actual length. 20 0 obj endobj 14 0 obj %%EOF MEMB113 | MANUAL DRAWING | CHAPTER 6 6.266..226.2 Isometric projection • Isometric projection is a true representation of the isometric view of an object • Isometric view is created by rotating the object 45 Darken all visible lines.

The term "isometric" comes from the Greek for "equal measure", reflecting that the scale along each axis of the projection is the same (unlike some other forms of graphical projection).. An isometric view of an object can be obtained by choosing the viewing direction such that the angles between the projections of the x, y, and z axes are all the same, or 120°. See more ideas about isometric drawing exercises, isometric drawing, drawing exercises. The angles between the isometric axes, therefore, must be 120 degrees.
