Answer 2

Answer:

The term "isometric" comes from Greek for "equal measure", reflecting that the scale along each axis of projection is same (unlike some other forms of the graphical projection).

An isometric view of the object can be obtained by choosing viewing direction such that the angles between projections of the x, y, and z axes are all same, or 120°. For example, with a cube, this is done by the first looking straight towards one face. Next, the cube is rotated at ±45° about the vertical axis, followed by the rotation of approximately 35.264° (precisely arcsin 1⁄√3 or the arctan 1⁄√2, which is related to Magic angle) about the horizontal axis. Note that with cube (see image) the perimeter of resulting 2D drawing is a perfect regular hexagon: all black lines have equal length and all the cube's faces are same area. Isometric graph paper can be placed under the normal piece of drawing paper to help achieve effect without calculation.
