- 2. Introduction to CAD Modelling CAD Modelling revolutionizes the design process by using software to create virtual 3D models, enabling efficient visualization and collaboration. Computer-aided design (CAD) is a technology that allows designers to create, modify and analyze 2D & 3D models of products using computer software. CAD software can help designers test, refine and manipulate virtual products before production, ensuring quality and accuracy for production. CAD modeling is the process of creating these high-quality 3D designs that are identical in dimension and detail to the desired finished product . If someone is interested in learning more about CAD software, Autodesk offers a range of 2D & 3D CAD software products that can help you draft construction documentation, explore design ideas, visualize concepts through photorealistic renderings and simulate how a design performs in the real world. ANDESIGN also offers CAD modeling services for 3D printing, prototyping, photo-realistic rendering and more.
- 3. Basic Tools and Techniques AUTOCAD The industry-standard software for 2D drafting and 3D modelling, offering a wide range of tools and functionalities. Solidworks A powerful tool for mechanical design, featuring robust parametric modelling capabilities for complex assemblies. CATIA Preferred by automotive and aerospace industries, CATIA enables advanced surface modelling and simulation capabilities. SEIMEN NX UG NX provides an integrated suite of CAD, CAM, and CAE tools for designing and simulating complex products.
- 4. AUTOCAD AutoCAD is a 2D and 3D computer-aided design (CAD) software application for desktop, web, and mobile developed by Autodesk. It was first released in December 1982 for the CP/M and IBM PC platforms as a desktop app running on microcomputers with internal graphics controllers. Initially a DOS application, subsequent versions were later released for other platforms including Classic Mac OS (1992), Microsoft Windows (1992), web browsers (2010), iOS (2010), macOS (2010), and Android (2011). AutoCAD is a general drafting and design application used in industry by architects, project managers, engineers, graphic designers, city planners and other professionals to prepare technical drawings. AutoCAD's native file formats are denoted either by a .dwg, .dwt, .dws, or .dxf filename extension. The system requirements for AutoCAD depend on the version of the software you are using. According to the official Autodesk website, the following are the system requirements for the latest version of AutoCAD, AutoCAD 2024: Operating System: Windows 10 or Windows 11 (64-bit only.) Processor: 64-bit; Intel or AMD. RAM: 8 GB as a minimum, with 16GB being recommended. Graphics Card: A dedicated graphics card that has been officially certified. Storage: 7 GB of free disk space for installation.

- 6. Solidworks SolidWorks (stylized as SOLIDWORKS) is a brand within Dassault Systèmes that develops and markets solid modeling computer- aided design, computer-aided engineering, 3D CAD design and collaboration, analysis and product data management software. The SolidWorks brand was founded as Winchester Design Systems by Massachusetts Institute of Technology graduate Jon Hirschtick on December 30, 1993. Jon and cofounders Dr. Constantine Dokos, Scott Harris, Bob Zuffante, Mike Payne and Tommy Li aimed to create 3D design software that was affordable, easy to use, and available on a Windows NT personal computer. SolidWorks developed the world's first 3D CAD solution that ran on a desktop PC. They had a simple mission statement of "3D on every engineer's desktop”. The system requirements for SolidWorks depend on the version of the software you are using. According to the official SolidWorks website, the following are the system requirements for the latest version of SolidWorks, SolidWorks 2024 : Operating System: Windows 10 or Windows 11 (64-bit only). Processor: 64-bit; Intel or AMD. RAM: 16GB or more. Graphics Card: A dedicated graphics card that has been officially certified. Storage: An SSD is recommended for optimal performance.
