It creates a distorted appearance by lack of foreshortening.There are following disadvantages of this projection such as In terms of measurement, it provides accuracy.To scale along principal axes measurement can be made.Illustrates the 3D nature of the object.This projection doesn’t need multiple views.There are following advantages of this projection such as The dimensions are less than the actual ones as a result and it is to be multiplied with 82/100 to get isometric dimension from the actual dimension. The isometric drawing and isometric projection drawing method are the same but all the dimensions in isometric drawing are actual while the isometric scale is to be used in the isometric projection. Difference between Isometric Drawing and Isometric Projection: The points of intersection of the corner of the bigger angle of the isometric square and the sides confronting it and by drawings arc the circle is completed. The isometric square is constructed for drawing the circles, then the four centers of an ellipse are shown and isometric circles are also not the actual circles but these circles are elliptic. To the axes, the lines which are drawn parallel in forming isometric projection are known as isometric lines and to the actual length, the represented length is not equal. So, this is the way from which the isometric scale is prepared. To represent the isometric scale draw perpendicular offsets from 45° line up to 30° line.According to the actual scale put marks on the 45° line.Draw two lines at 45° and 30° after drawing a horizontal line.There are following methods used for the drawing of isometric scale such as To form an isometric projection the isometric scale is prepared and the actual dimensions are transformed into isometric dimensions with the help of this scale. The isometric lines make the angle of 30° with the horizontal line in isometric projection and their length is not equal to the actual length.
