That's what an isometric drawing is: the third dimension is shown at a 30 degree angle to the horizontal.

The number 30 isn't magic - any other number in that 'ballpark' would work - but it's an easy number ( a third of a right angle, and it's clearly different from 60 degrees, which is why 45 degrees wouldn't be great), and the resulting drawing makes the 3-D object easy to visualize.

Why 30 degree angle is used in isometric?

isometric drawing create the illusion of 3 dimension by drawing the depth of the object on the both side.. in isometric drawing they are both set on the 30 degree angle..


What angle should be drawn on a isometric drawing?

30 degree's and 30 degrees


What is the difference between isometric and oblique drawing?

1.)Oblique sketch has a more focus on the front side of an object or the face while isometric sketch focuses on the edge of an object. 2.)Oblique sketch drawn usually using the 45-degrees angle to render the third dimensions while isometric sketch drawn using 30 degrees angles.


How will a circle appear on an isometric drawing?

An isometric view necessarily should have two side views and either top or bottom view incorporated to be drawn in a single drawing. In order to represent top 0r bottom view a 30 degree angle from horizontal will be established as an inclined plane. Hence where the circle has to appear is important. Any how in order to get a circle in an isometric view an oval or elliptical form should be present in any one of the first angle or third angle views.


Does an isometric drawing use a vanishing point to create depth?

No. Isometrics are created using equal angles. Isometric drawings were made on "iso paper" but it is really just 45 degree lines on a page.


How do you draw an isometric train?

I do not know!!!!:( If you are drawing an isometric drawing by hand (pencil / paper), go purchase a 30 / 60 / 90 triangle (don't forget to use a straight edge to align the triangle). If you are using CAD, change your snap to Isometirc and use CTRL + E to rotate between the planes (top, left, right). Also use crating to help you draw curves!!

What is isometric sketching?

Isometric view is a two dimensional representation of a three dimensional object or space. It is often used in technical drawings, such as architectural, engineering and patent drawings. It is similar to perspective view, yet isometric drawings do not converge at a vanishing point. Since perspective is an optical illusion that skews the lines and dimensions of an object, it cannot be used to convey technical data (i.e., the exact size and measurements of an object, surface or space). In isometric drawings, however, the lines remain parallel and proportionate to one another. It conveys an illusion of three dimensional space without modifying the dimensions and scale of an object. Therefore, it can be used as a scaled technical drawing. Visually, an isometric view consists of two elevations (A and B) that are adjoined at one side (the y axis) and a plan view (C) that is joined at the top or bottom of elevations A and B. All vertical lines are drawn at an angle that is perpendicular to an imaginary horizon line (the x axis). All horizontal lines, however, are rotated along the y axis at a constant angle (usually 30 or 45 degrees). If the horizontal lines in elevation A are rotated to 30 degrees (taken from the x axis), then the inner angle will be 60 degrees (taken from the y axis). On the opposite side of the y axis, elevation B is mirrored at the same angle (30 degree outer and 60 degree inner). The sum of the inner angles (60 + 60) then forms the angle of the adjoining plan C (120 degrees). For a 45 degree isometric, the inner angles of elevations A and B are each 45 degrees and the adjoining angle of plan C is 90 degrees.
