Why use CAD or AutoCAD for Civil engineering design and drafting?
Civil Engineers design and develop modern home and commercial buildings. The design building models and implement those using assets and technologies. Presently, designs are made digitally using computer-aided design (CAD) software. CAD drafting has made a civil Engineers job simpler and simpler which was much more complex earlier when done manually. CAD software such as AutoCAD, Revit, Tekla, etc has become an integral part of the industry. In the future well ahead and creative features should make CAD software more functional and a complete product to fulfil raising expectations and the needs of this industry.
All through the years, CAD software has always been evolving which resulted in lesser designing time and simpler drafting process for the Engineers. Automated CAD drafting makes high-feature designs accurately and quicker. The Engineer can analyze the project model, and the changes can be incorporated in the design easily, saving a lot of time and money. The functionality of the software can be enhanced by integrating it with other useful applications. This compensation of the CAD software increases the efficiency of drafting to a fantastic amount. But, CAD software also has demerits as it is expensive and training is very essential for AutoCAD drafting.

The civil Engineer can design a 2D or 3D building model. 3D modelling compared to 2D drafting is much well ahead as it makes more complex objects. AutoCAD 3D software is based on solid and parametric modelling and grown-up wireframe practice. The solid modelling makes basic solid structures. They have limited motion and lack of intelligent features. Modern 3D parametric modelling defines other models using well ahead geometric features. It employs transmigration operation with which the design can be changed anywhere. These changes affect other design parts and have to be adjusted accordingly. Consequently, the original design indent becomes valuable while drafting to dodge corrections and changes in the design. But this conundrum can be eliminated by explicit modellers.
3D modelling has greater compensation over 2D drafting. 3D designs are quicker and of the high feature. The rendering aids help to produce a photorealistic, dynamic and accurate design. Manipulations in the 3D design can be done instantly. With 2D design the visualization is hard, and there is always a possibility of error in the output. In spite of all these shortcomings, 2D CAD software is still used in the meadow of Civil engineering.
