The lines drawn parallel to the isometric axes are known as Isometric Line. Any other line which is not parallel to any of the isometric axes is known as Non-Isometric Line. The lines XY, YZ & ZX are called non-isometric lines.
What is a non-isometric line?
Any other line which is not parallel to any of the isometric axes is known as Non-Isometric Line. The lines XY, YZ & ZX are called non-isometric lines. Since these lines are not parallel to the isometric axes, they are not foreshortened in the same proportion as the isometric lines.
What are the different lines in isometric projection?
Lines in Isometric Projection 1 The lines which are parallel to the object are parallel at the isometric projection. 2 Vertical lines on the object appear vertical at the isometric projection. 3 Horizontal lines on the item are drawn at an angle of 3 0° with the horizontal at the isometric projection.

What is a normal line in an isometric drawing?
Recall that a normal line is a line that, in a normal multi-view projection, is parallel to two of the planes of projection and perpendicular to the third. Thus, Figure 5-39.-Use of "box construction" in isometric drawing. Figure 5-40.-A non-isometric line (AB) in an isometric projection.
How are drawing limits set in a non-isometric drawing?
They are located by determining the endpoints of the non-isometric line. They are measured using a non-isometric template. In order to set drawing limits for a "C" size architectural drawing the drafter should set the limits to ________. The standard number of threads per inch for various diameters is the:
What are isometric lines?
Definition of isometric line 1 : a line representing changes of pressure or temperature under conditions of constant volume. 2 : a line (such as a contour line) drawn on a map and indicating a true constant value throughout its extent.
What is a non-isometric line?
These lines are called Isometric Axes. In the figure, the lines which are parallel to these lines are called isometric lines, and those lines which are not parallel to these lines are called Non-isometric Lines.
What is isometric lines in drawing?
An isometric drawing is a 3D representation of an object, room, building or design on a 2D surface. One of the defining characteristics of an isometric drawing, compared to other types of 3D representation, is that the final image is not distorted. This is due to the fact that the foreshortening of the axes is equal.
How are non-isometric?
They are measured using the angle from the multiview. They are drawn parallel to the isometric axis. They are located by determining the endpoints of the non-isometric line.
What are the examples of isometric drawing?
Solution: Technically the Isometric projection is the two-dimensional representation for viewing a 3-D object with the three primary lines, which are equally tilted away from the viewer. Thus an example of isometric projection is the technical drawing of a house or building.
Are isometric lines true length?
What is the true length of it? Explanation: The ratio of isometric length to true length is 0.815 so here it is given isometric length of 20 cm. 0.815 = 20 cm / true length => true length = 20 cm /0.815 = 24.53 cm. Every time the true length is more than isometric length.
What are the 3 isometric drawings?
The term "isometric" is often mistakenly used to refer to axonometric projections, generally. There are, however, actually three types of axonometric projections: isometric, dimetric and oblique.
Why are isometric drawings used?
Isometric drawings are commonly used in technical drawing to show an item in 3D on a 2D page. Isometric drawings, sometimes called isometric projections, are a good way of showing measurements and how components fit together. Unlike perspective drawings, they don't get smaller as the lines go into the distance.
How are non isometric lines located and sketched?
2) Non-isometric lines are located and sketched how? they are drawn parallel to the isometric axis. they are measured using the angle from multiview They are measured using non-isometric template They are located by determining the endpoints of the non-isometric line.

What is difference between isometric view and isometric projection?
In isometric view or drawing, the object is shown or viewed in drawing with the actual dimensions with normal scale. In isometric projections, the plane is placed in such a manner that one can observe all the angles of projections.
How many types of isometric drawings are there?
three typesAn isometric drawing is one of three types of axonometric drawings. It is created on the basis of parallel projection technique. The other two types of axonometric drawings are dimetric and trimetric drawings. In isometric drawings, the three principal axes make equal angles with the image plane.
What kind of lines do you use in isometric drawing?
An isometric drawing is created using three axes. The three axes are formed from a vertical line with two horizontal lines at 30-degree angles. The vertical line is blue, and the horizontal lines are red and green, created at 30-degree angles to form the vertical line.

What is isometric and orthographic view?
Isometric: a method of representing three-dimensional objects on a flat surface by means of a drawing that shows three planes of the object. Orthographic: a method for representing a three-dimensional object by means of several views from various planes.
What are the characteristics of isometric drawing?
In an isometric drawing, the object appears as if viewed from above from one corner, with the axes being set out from a corner point. Isometric drawings begin with one vertical line along which two points are defined. Any lines set out from these points should be constructed at an angle of 30 degrees.
What is a line that is not parallel to an isometric axis?
A line that’s not parallel to any isometric axis is known as the non-isometric line, and the extent of the fore-shortening of non-isometric lines is different if their inclinations with the vertical planes are different.
What Is Isometric Scale?
An isometric scale can be used to draw correct isometric projections. All distances in this scale are 2/3 × true size, or approximately 80% of true size. Figure 3.40a shows an isometric scale.
What is isometric projection?
Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees.
What is the ratio of isometric axes?
The isometric axes are reduced in the ratio 1:0.816, i.e., 82% approximately.
Why is isometric perspective advantageous?
This is advantageous because the measurement could be made directly from a drawing.
What angle is the horizontal line drawn at?
Horizontal lines on the item are drawn at an angle of 3 0° with the horizontal at the isometric projection.
Is the isometric drawing of the figure larger than the isometric projection?
The isometric drawing of the figure is slightly larger (approximately 22%) than the isometric projection. Since the proportions are the same, the increased size doesn’t affect the pictorial value of this representation, and at the same time, it might be done quickly.
