Isometric drawing vs one-point perspective How to draw an isometric cube Isometric drawing examples. Isometric drawing is a form of 3D drawing, which is set out using degree angles. It is a type of axonometric drawing so the same scale is used for every axis, resulting in a non-distorted image.
Since isometric grids are pretty easy to set up, once you understand the basics of isometric drawing, creating a freehand isometric sketch is relatively simple. This post explains all you need to know about isometric drawing. You'll learn exactly what defines an isometric drawing, how it differs from one-point perspective, what to do to get started creating your own isometric projection, and even more.

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. The word isometric comes from Greek to mean 'equal measure'. Isometric drawings differ from other types of axonometric drawing, including dimetric and trimetric projections, in which different scales are used for different axes to give a distorted final image.
In an isometric drawing, the object appears as if it is being viewed from above from one corner, with the axes being set out from this 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.
Both isometric drawings and one-point perspective drawings use geometry and mathematics to present 3D representations on 2D surfaces. One-point perspective drawings mimic what the human eye perceives, so objects appear smaller the further away they are from the viewer. The front view of this cube, resting on one of its corners G , is the isometric projection of the cube.
The isometric projection of the cube is reproduced shown in the below figure In the isometric projection of a cube shown in the show above figure-2, the top face ABCD is sloping away from the observer, and hence the edges of the top face will appear fore-shortened. The extent of reduction of an isometric line is easily found by the construction of a diagram known as isometric scale. For this, reproduce the triangle DPA as shown in the show below figure Mark the divisions of true length on DP.
Through these divisions, draw vertical lines to get the corresponding points on DA. The divisions of the line DA give dimensions to isometric scale. The following are the relations between the lines in isometric projection which are evident from the show above figure-2 An Isometric Cub.
Shows in below Figure a rectangular block in pictorial form and Shows in below Figure b , the steps for drawing an isometric projection using the isometric scale.
Drawing of objects are seldom drawn in true isometric projections, since using an isometric scale is inconvenient. Instead, a convenient way in which the foreshorten-ing of lengths is ignored and actual or true lengths are utilized to obtain the projections, known as isometric drawing, or isometric perspective is normally utilized. This is advantageous because the measurement could be made directly from a drawing.
HINT Draw your shape from back to front and from bottom to top, to assure proper alignment of cubes. When adding adjacent cubes, be sure to click on the face of the cube you want to be touching. Create Mode There are two ways to move objects:. Rotate the entire figure by dragging the image or by using the sliders.
Use the Eraser to erase individual objects. You can also select multiple objects with the Pointer and then use the eraser to erase those objects. Explode - Change all cubes into faces. If two cubes share a face, the face will not be shown. Note that you can not undo this action. Use the Paint Brush to select a color before you create an object. You can also change the color once an object is created by selecting the object with the color you wish it to be.
The picture below shows three views of a figure from the front, right, and top. The entire figure uses a total of seven cubes. Can you construct the figure using the isometric drawing tool?
