Isometric: Isometric Drawing and its characteristic
Posted On 03/03/2020 04:37:10

It is one of the forms of projection used in technical drawing like REVIT MEP Design that has the advantage of allowing scale representation. Isometric determines a visualization direction in which the projection of the coordinate axes x, y, z make up the same angle, that is, 120º from each other. The objects are shown with a rotation of the viewpoint of 45º in the three main directions (x, y, and z).

This perspective can be visualized considering the point of view located at the top vertex of a cubic room, facing the opposite vertex. The x and y axes are the straight lines of the encounter with the floor, and the z axis, the vertical, the encounter of the walls. In the drawing, the axes (and their parallel lines), maintain 120º between them.


Within the set of axonometric or cylindrical projections, there are other types of perspective. Which differ by the position of the main axes, and the use of different reduction coefficients to compensate for visual distortions.

Isometric Drawing:

Isometric refers to that three-dimensional drawing that has been made with the inclined axes forming an angle of 30 ° with the horizontal. One of the great advantages of P&ID Diagram is that the drawing of any model can be made without using any special scale, since the lines parallel to the axes are taken in their true magnitude. Thus, for example, when the cube is drawn in an isometric way, it has all its edges of equal measure.

A widely used variety of the Isometric Perspective is the Isometric Drawing. In the Isometric one the coefficient of reduction of the dimensions equivalent to approximately 0.816, that is to say, along the axes a real dimension 1 is multiplied by that factor. Being the identical reduction in the three axes, the isometric drawing is made without reduction, with the dimensions parallel to the axes at 1: 1 scale or natural scale. Without changing the appearance of the drawing except in its size.

This allows both to draw these dimensions directly on paper (which facilitates drawing by Cartesian coordinates and directly measuring those of an object in the drawing. The appearance of the drawing is identical although larger, and the dimensions that in the correct perspective would be equal to the real ones (those parallel to the projection plane) are larger. The scale on which the Isometric Drawing is larger compared to the Isometric Perspective is approximately 1.22.

Characteristics of the Isometric Drawing:

An isometric drawing is not an isometric viewpoint, since it is done without any reduction. This, like the isometric perspective, reveals the faces of the solid in the three sectors of the axes, with the same amplitude. We can also make Structural Steel Detailing with isometric drawing.

Axes used in the Isometric Drawing: The basis of the isometric drawing is a three-axis system called "isometric axes" that represent the three edges of a cube, which form 120 ° angles

Isometric Lines: Are those lines that are parallel to any of the three isometric axes

Non-Isometric Lines: They are those inclined lines on which true distances cannot be measured. When these lines are present in an isometric drawing, they are neither along the axes nor parallel to them.

Importance of draftsmanship these days
Posted On 02/10/2020 06:19:59

Drafting is a way creating accurate representations of objects or buildings or houses for the purpose of architecture, engineering etc. To build up a house or buildings or to make cars or other vehicles, the need of a draftsman for Industrial Structure Design is inevitable. In drafting, different objects are drawn to measure, and it is usually drawn from the top view, a main view and definitely a side view of the objects. Drawing helps the engineers a lot to speed up their work. There are lots to this Product Design Agency. This process of drawing helps to get a picture of mining, automotive, defense, oil, gas, and water industries as well.


Demand of draftsmanship in different fields:

Detailing is a big responsibility. It is to understand that there is a lot difference in the demands of craftsman in the field of engineering and in the field of architecture. While engineering requires the help of Gearbox Design Services often, draftsmanship is more than a common used name in architecture. Engineers or the companies appoint draftsmen as to draw the skeleton of a building but on the other hand architectures engage them to sketch down whole buildings and their patterns with minute details including dimension of the buildings. The draftsmen use pencils and blueprints to give their drawings and Solidworks 3D CAD vibrant look.

Works of the draftsmanship:

Draftsman companies are consisted of qualified and experienced service men. They provide their clients with suitable and perfect pictures of their buildings or vehicles. The men usually use traditional way to make the drawings. Technical drawings are usually made up on the papers with pencil, rulers and of course with the help of a protractor. But in the recent time, the designs and patterns are made with computer or CAD. The use of Plant Engineering Services and CAD method represents three dimensional images before the clients of their respective projects. With the help of draftsmanship, many different things are designed and they are:

  • Specifications for the windows
  • Specifications for doors
  • Designs of lights and appliances
  • Details of the driveways, gardens, fencing and type of the roofs etc are represented with drawings

It is really very important to engage a draftsman if you are in the engineering or if you are in the business of architecture. Find out a suitable service as early as possible.

Three dimensional model:

Until the recent time, drawings used to be made with the help of pencil, paper, and rulers and with protractors, but the picture is different of late. Now with the development in the field of technology, we have come to the touch of computer graphics and three dimensional technologies. Since the time, this three dimensional technology has been introduced in the market, we have witnessed a huge revolution in the field of drafting or drawing services for the purpose to serve engineering and architecture. There are two types in three dimensional techniques; one is low-poly three dimensional techniques and high-poly three dimension technique. Three-dimensional content is required for different purposes to meet.
