But if finite element analysis, topology optimisation, generative design, etc. Some software can get really bulky, demanding higher storage and computer processing power from the user. Modern CAD software provides a wide range of features. Most free CAD software does not have a specific focus but they still differ from one another. Some software is designed with lots of functionalities that can be used in a variety of fields (general-purpose software such as SolidWorks), while others are designed with a focus on specific niches such as automobile design (e.g. Companies create CAD software with a certain target audience in mind. This is the most important factor that will determine the best CAD software for one’s needs. One must ask himself the following questions to choose the right CAD software for himself. The best CAD software for an application changes from case to case as it depends on many factors such as the desired capability, pricing, application, and ease of learning. There are many different types of CAD programs available in the market. Making small changes to see how they improve the overall aesthetics and functionality of the product is made very easy.Īll these great advantages with little to no disadvantages have made 2D and 3D CAD software a necessity in modern design setups. The designers can rectify any design errors in the 3D models before the manufacturing phase begins. The software allows us to create highly complex 3D designs that can take full advantage of the CAM possibilities of today to deliver truly amazing results.Ĭomputer-aided design software further provides many additional functionalities such as analysis, modification, and optimisation of the design prior to manufacturing. In recent years, its ability to ensure communication/collaboration through cloud storage and seamless integration with CAM and CAE systems has significantly increased its proliferation and ubiquity through the design space. From being a coveted luxury in design, CAD software is now the default design tool in all sectors of engineering. V Conclusion What Makes Computer-Aided Design Software a Necessity for Engineers?Ĭomputer-aided design software has pretty much completely replaced manual drafting.
