Civil Engineering involves designing and drafting drawings of buildings, roads, dams and such other man made constructions. In the past, the design and drafting of these drawings used to be done by hand. However, nowadays many different software programs provide the CAD (Computer Aided Drawing) facility to civil engineers, designers and draughtsmen to create their drawings and designs.
There are many advantages to using CAD or AutoCAD (a CAD software program) for civil engineering design and drafting. Chiefly, the advantage is in the process of implementing changes within the drawing. Previously, when changes had to be implemented within the drawing, the engineer had to redraw the entire drawing by hand. However, using CAD or AutoCAD gives the engineer the advantage of simply making those changes in a computer program, and then just rendering the drawing again.
The time and effort that gets saved by using CAD or AutoCAD within the design and drafting process then leads to huge savings in the production timelines and also in the costs. Naturally, CAD and AutoCAD have gained and earned their place within the design and drawing process.
CAD and AutoCAD software programs can also create more accurate renderings of the drawings and designs. These software programs allow engineers to use complex objects within their drawings, and use techniques such as parametric and solid modeling techniques along with wireframe techniques to render a drawing.
The CAD and AutoCAD software programs also have a variety of rendering aids that help create very realistic and accurate renderings of the drawings - which more or less creates an almost actual picture of the building that will be constructed.
Along with these obvious visually oriented benefits, CAD and AutoCAD software also offer a variety of in-built documentation reports. These are beneficial on several levels as they are based on the data used while creating these designs and provide businesses with a variety of intelligent and informative reports which prove to be extremely useful during the planning and implementation stages of the actual construction process.
Thus, one can easily see that there are a number of benefits of using CAD or AutoCAD for the civil engineering design and drafting process: savings in terms of time and costs, along with added advantages in the visualization and documentation outputs of the design.
