This leads to many users looking for free 3D CAD software or professional-grade software with extended trial periods. In many cases, the monthly subscription fee of 3D CAD software can be significantly higher than the lifetime fee of a 2D CAD alternative. All in all, this has proven to speed up the design process by 45% compared to 2D drafting programs.īut these CAD programs can be costly. The advanced features of 3D CAD have become essential tools from the point of mechanical engineering. We will be starting out with 3D CAD software. The development team is active and regularly introduces new features to keep up with the latest trends.Can import/export all relevant file formats.It is natively interoperable with relevant solutions such as simulation.The CAD program’s feature set meets all your needs.If you are an advanced user, you need to give thought to features such as: An active online community for common questions.A uniform interface throughout the program.Features that help beginners must be given preference. If you are a student and/or a beginner, it might be better to start with CAD software with a short learning curve. Writing down a list of your desired features can significantly narrow down the search for the perfect CAD software for you. It is best to opt for features that are most relevant to the application that the software will be subjected to. are all part of your project flow, these features can be found in many CAD packages. 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. FreeCAD is available for Windows, macOS, and Linux.V Conclusion What Makes Computer-Aided Design Software a Necessity for Engineers?Ĭomputer-aided design software has pretty much completely replaced manual drafting. The interface can also be a little daunting for complete beginners. The only pitfall of FreeCAD is its underwhelming 2D capability. In addition, being aware of some common Python functions can further enhance your experience with FreeCAD.īeing open-source, FreeCAD has an active community of users that help and support each other. Using this, you can record macros, code your own tool, and create full-fledged custom workbenches. FreeCAD also allows you to export your project to external renderers.įreeCAD is particularly suited for users familiar with Python, as it has an integrated Python console. While the program has all the features you may need as a designer, many additional features can be added using plugins. This open-source software is primarily focused on 3D parametric modeling but also offers limited 2D capabilities. FreeCAD consistently tops the list when it comes to free CAD programs, and for a good reason.
