Question

the ratio of isometric view of isometric projection

Answer 1

Answer:

Step-by-step explanation:

Image result for the ratio of isometric view of isometric projection

The black dimensions are the true lengths as found in an orthographic projection. The red dimensions are used when drawing with the isometric drawing method. The same 3D shapes drawn in isometric projection would appear smaller; an isometric projection will show the object's sides foreshortened, by approximately 80%.

Answer 2

The ratio of isometric view to isometric projection is same as the ratio of isometric length to the true length. So ,If we represent a cube in isometric view the diagonal of upper face of cube is equal to the true length of the diagonal. From it by drawing an actual square around it and then calculating it gives (1/cos 30)/ (1/cos 45) =isometric /true =0.815.That is the required answer.
