75 AutoCAD is a commercial software application used to draft 2-dimensional and 3-dimensional models with the aid of a computer. It is used for a large number of different design processes. Its usage centres around drawing with electronic equivalents of real-life drafting tools. The added support of digital precision helps with measurements and calculations, 3D components, and data sharing. Analysis TYPES OF CAD Choosing the right CAD software is fundamental for design efficiency. To decide effectively, specific needs and goals must be accurately defined and the project requirements must match the features of the software. Detail Design 178 MeCHAniCs Fabrication Conceptual Design Main cateogories Having multiple applications, there are several types of CAD, which can be divided into two main categories: Site Analysis Construction BUILDING INFORMATION MODELLING Construction Logistics Programming 2D CAD was developed in the early 70 s and is still used to create flat drawings of products and structures. Objects created in 2D CAD are made up of lines, circles, ovals, slots, and curves. Among the most popular 2D CAD programs are AutoCAD , CADkey, CATIAv4, and Medusa; to break ground: iniziare i lavori to come down to: dipendere contractor: impresario, appaltatore flat: piatto slot: fessura Documentation 3D CAD programs come in a wide variety of types, intended for different applications and levels of details. Some 3D CAD programs include Autodesk Inventor, CoCreate Solid Designer, ProE, SolidWorks, SolidEdge, and VX CAD. From CAD to CAE Computer-Aided Engineering (CAE) involves the use of computer software to improve product design and solve engineering problems for a wide range of industries. This can include simulation, optimisation, and validation of products and processes. It is used to both design and support the engineering process for a product, allowing tests and Renovation Operation & Maintenance simulations to be performed without the need for a physical prototype. So, if CAD is used for designing a product, CAE is used for testing and simulating it. What is BIM? A further development is represented by BIM, which stands for Building Information Modelling. Many building and design professionals are moving from CAD to BIM applications because of its advanced capabilities for modelling. BIM, in fact, is a new process and methodology by which a team of architects, engineers, and contractors work collaboratively to design and build a commercial building using the same database and computer models; this allows the team to analyse and visualise design decisions long before a project even breaks ground. BIM or CAD? Choosing between BIM or CAD comes down to every project. CAD is generally used for the industrial design of mechanical and electrical assemblies, from airplanes to smartphones; BIM is used in the design and construction of commercial buildings like airports, office towers, or schools.
