1.  Introduction to CAD in Civil Engineering

Computer aided Design (CAD) is a process of preparing a drawing of a structural plan on a computer using specialized software or application. It can be defined as the use of a system to assist design in the creation, modification, customization, analysis and overall optimization of a design work.

For civil engineers, CAD is the starting point of creativity, bringing out the first line of imagination into a tangible structure. It plays a crucial role in surveying for collecting and analyzing geographical data. This data determines all sects of civil engineering projects, from initial planning to final construction.

Today, it’s nearly impossible to find a civil engineer without CAD knowledge or training. No wonder, the traditional or manual design methods are simply lagged behind in the fast pace of machine technology.

History of CAD

The journey of CAD was originally started back with PRONTO in 1957, the first commercial numerical-control programming system, which was developed by Dr. Patrick J. Hanratty.

Later, In 1960. Ivan Sutherland upgraded to 3D computer modeling and visual simulation, called SKETCHPAD which is the main basis for today’s CAD application. It demonstrated the basic principles and feasibility of computer technical drawing.  For the first time, A designer was able to draw engineering drawings with a pen directly on a digital CRT screen.

2.  Significance of CAD in the Field of Civil Engineering

“Failing to plan is planning to fail.”

It is known ‘Well planned is half done’ so, we usually create a plan before starting any building, structure or design. Of course, designs often require multiple rounds of editing and refinement. CAD allows an engineer to edit, refine and make any changes in his design as much as he wants. It is the most significant and widely used tool for an engineer to create any design in level of expertise.

Additionally, professional or business infrastructure is a matter of huge investment. The investors and owners must deserve, by default, the cost effectiveness and security on their capital investment.

With advanced features such as 3D modeling and simulation of CAD applications, engineers can render the live visualization of any civil construction, architectural forms in virtual space, so that we can know for sure what we are going to do exactly.

The quick ability to make intricating changes in design is the major advantage of CAD making it easier to identify potential flaws and optimize issues. In traditional design methods, even creating 2D designs is time consuming and inaccurate.

Apart from the intricacy of designs, and saving time required to any project, CAD helps us to make as many alterations, additions or redrafts as we may need. Mostly, it cuts out far less effort than we’d require with traditional sketches.

CAD supports collaboration among project associates, as designs can be easily shared and modified in real time. In this way, the use of CAD also contributes to cost savings and increased efficiency, making it an essential tool in modern civil engineering practices.
