A line in isometric drawing that is not parallel to the isometric axis is called a non-isometric line. This is called the isometric line and its length is reduced by 82%. A line is drawn parallel to the isometric axis of the object. The parallel lines on the object are parallel to the isometric projection. The relationship between the lines of isometric projection is clear from the instructions below, The isometric axes are reduced in the ratio 1:0.816, i.e., 82% approximately.Īlso Read : What Is a Skeleton Frame? | What Is Building Skeleton? | Use of Steel Frame Structures | Advantages & Diaadvantage of Steel Frame Construction Lines in Isometric Projection The correct length of the isometric length is obtained by the ratio of the triangle ADO and PDO, above Figure 2 (Isometric cube). The sections of giving parameters to the isometric scale. The sections of the line DA give the parameters of the isometric scale. The scale of this figure draws vertical lines to suit the isometric length. For this, triangle DPA is formed as shown in Fig. The isometric scale can easily be found in the reduction of the isometric line by the construction of the figure. Using this scale, the actual dimensions of the object are converted to isometric dimensions. But it is only 80 percent shorter than the actual length.Īn isometric projection is formed using an isometric scale. So the length of the object is not equal to the actual length. 
In isometric projection, the isometric lines for the object are drawn with an angle of 30 horizontal planes.
It shows the isometric projection of a cube by ABCDFGH points.Īlso Read : What Is Oblique Drawing? | Oblique Projection | Procedure for Oblique Drawing – Example | Types of Oblique Drawing Isometric Scale The isometric projection of the cube is shown in the figure.
In the isometric projection of an object, the three axes of the projection passing through those solid particles of the cube form a transparent cube with a horizontal plane. It is an illustrated orthographic projection of an object in which a transparent solid containing the object is tilted in such a way that the solid diagonal of the cube is perpendicular to a vert plane and the three axes are inclined towards the plane.
