The history of engineering drawing can be traced back to the days when engineers used paper and pencil to illustrate their designs.

Today, engineering drawings are digital files that are used to make precise 3D models of equipment and structures. The development of engineering drawing software has allowed engineers to create drawings faster and more accurately than ever before.

## a history of engineering drawing

Complex technical drawings were made in renaissance times, such as the drawings of Leonardo da Vinci. Modern engineering drawing, with its precise conventions of orthographic projection and scale, arose in France at a time when the Industrial Revolution was in its infancy.

### Technique for sketching in perspective

When sketching in perspective, it is important to take into account the vanishing point. This can be determined by drawing a line from the viewer’s eye to the object being viewed.

The line will intersect the object at a point called the vanishing point. When drawing objects in perspective, it is important to maintain this vanishing point as you draw. If an object is too far away from the viewer, then its outline will appear distorted. Conversely, if an object is too close to the viewer, its outline will appear too small and squished.

### Geometry that is descriptive

There are many different types of geometry, each with its own specific purpose. One type of geometry is used to create drawings and diagrams.

Geometry can help designers create accurate representations of objects and spaces, which is important for many fields such as engineering and architecture.

### the projection of an orthographic plan

Orthographic projection is a graphical technique used in engineering drawing and mapmaking that enables the drawing of 3-dimensional objects on a flat surface.

The basic principle behind orthographic projection is to use a fixed reference point, usually the center of the Earth, and to project lines onto a two-dimensional plane so that they appear to converge at the reference point. This technique is often used in engineering drawings to show how structural elements, such as columns or beams, would look if placed in an actual scene.

### Design using a computer-aided program

Design is the process of creating a plan or concept for an object, system, or product. The process of designing something can be done using a computer-aided program (CAD).

CAD programs allow people to create detailed drawings of objects and systems. This is helpful when trying to create something from scratch or when modifying an existing object. CAD also allows people to view various angles and views of their designs so that they can make sure that everything looks the way they want it to.

## Who is the father of engineering drawing?

Who is the father of engineering drawing?

But a French mathematician named Gaspard Monge is considered by many to be the founder of modern technical drawing. Monge’s thoughts on the subject, Geometrie Descriptive (Descriptive Geometry), published around 1799 became the basis for the first university courses.

## Who invented orthographic drawings?

Who invented orthographic drawings?

A drawing on the back of an envelope showing how to get from one street to another is the most universal and ancient type of drawing a flat outline known as orthographic. The full value of this system was not realised until Gaspard Monge invented multi-angle orthographic projection in the late 18th century.Sep 19, 2009

## FAQ a history of engineering drawing

### Who invented drafting?

Junior Johnson, at age 77, could see and feel and understand precisely what Jimmie Johnson, age 32 (no relation), was doing. It was Junior who discovered the phenomenon of drafting, invented the tactic, and became the first driver to win with it, in the second Daytona 500, in 1960.Jul 30, 2008

### Who invented engineering drawing?

Most early creators of engineering drawings were artists and inventors. Some of the best-known early engineering drawings are the work of Italian Leonardo da Vinci. Leonardo is well known for his art, such as The Last Supper in 1498 and the Mona Lisa in 1507.

### What are the three 3 basic types of technical drawings?

Three types of drawings are generally used. These are (i) computer program listing drawing, (ii) computer program assembly drawing, and (iii) computer program set drawing.Mar 8, 2017

### Why are there different types of drawings in engineering?

Different Types of Lines The different options make it possible to show both visible and hidden edges of a part, centre lines, etc. The most common is a continuous line, also known as a drawing line. This represents the physical boundaries of an object.Jun 18, 2020

### What are Level 3 drawings?

6.4. 3 Level 3, production. To provide engineering data for support of quantity production to permit competitive procurement for items sub- stantially identical to original items. These engineering drawings reflect technical data possessing the highest level of confidence.Oct 28, 1977

### What are the three types of engineering drawings?

Orthographic projections: are drawn as multi view drawings, which show flat representations of principal views of the subject. Oblique Projections: actually show the full size of one view. Axonometric Projections: are three-dimensional drawings, and are of three different varieties: Isometric, Dimetric and Trimetric.

### What is the purpose of engineering drawing?

Engineering drawings are used to communicate design ideas and technical information to engineers and other professionals throughout the design process. An engineering drawing represents a complex three-dimensional object on a two-dimensional piece of paper or computer screen by a process called projection.

## Conclusion

In conclusion, engineering drawing was first used in the 14th century and has been used ever since to communicate engineering designs. It is an essential tool for engineers and plays a critical role in the engineering design process.

Although technology has evolved over the years, engineering drawing has remained largely unchanged. It is still used today to create 2D and 3D drawings of objects and to communicate design ideas.
