Choosing the right CAD software is pivotal for design efficiency. To decide effectively, first define your specific needs and goals, then match software features to your project requirements. Next, check compatibility with your preferred file formats and other software in the design workflow, and, lastly, consider available learning resources such as tutorials, training, and a supportive user community.
Together, CAD and building information modeling (BIM) provide a powerful combination of digital tools that empower structural and MEP engineers to deliver safe, efficient, and compliant building projects.
Cloud-based CAD software operates over the internet, storing design data remotely and enabling access from various devices. This approach enhances collaboration by allowing real-time, multiuser work on projects while robust version control helps ensure design integrity. Users benefit from easy access to projects anywhere, reduced file-management complexity, automatic backups, and heightened security measures.
CAD software is used by a diverse range of professions that require design precision and visualization. Architects and landscape architects; engineers (across disciplines such as mechanical, civil, automotive, aerospace, and electrical); designers (including product, industrial, graphic, mechanical, interior, and jewelry); urban planners; and professionals in construction and surveying all rely on CAD. This software aids in creating detailed 2D and 3D models, schematics, layouts, and plans, empowering professionals to conceptualize, design, and optimize structures, products, and systems efficiently across industries.
CAD software is available in various types to serve diverse design needs. Technical drawings use 2D CAD whereas 3D CAD creates three-dimensional models for product design and architecture. Parametric CAD establishes relationships between elements while direct modeling offers flexible design modifications. Surface modeling crafts curved surfaces, and solid modeling defines volumes and mass. Rendering and animation software visualizes designs realistically. Building information modeling (BIM) focuses on architecture and construction, and electronic design automation (EDA) handles electronic systems. CAM generates manufacturing instructions, and specialized CAD types exist for plant design, fashion design, and more.

It enables the creation of intricate 3D models, optimizes them for printing, and generates compatible file formats such as STL. CAD tools facilitate the addition of support structures and help ensure model accuracy and scaling. By interfacing with slicing software, CAD helps divide models into printable layers and prepares them for 3D printing. The software also aids in prototyping, refining designs, and preventing errors before the final print.

Its use in designing electronic systems is known as electronic design automation (EDA). In mechanical design it is known as mechanical design automation (MDA), which includes the process of creating a technical drawing with the use of computer software.[3]
CAD software for mechanical design uses either vector-based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. However, it involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD must convey information, such as materials, processes, dimensions, and tolerances, according to application-specific conventions.
CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design (building information modeling), prosthetics, and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising and technical manuals, often called DCC digital content creation. The modern ubiquity and power of computers means that even perfume bottles and shampoo dispensers are designed using techniques unheard of by engineers of the 1960s. Because of its enormous economic importance, CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software), and discrete differential geometry.[6]
CAD is one part of the whole digital product development (DPD) activity within the product lifecycle management (PLM) processes, and as such is used together with other tools, which are either integrated modules or stand-alone products, such as:
CAD is also used for the accurate creation of photo simulations that are often required in the preparation of environmental impact reports, in which computer-aided designs of intended buildings are superimposed into photographs of existing environments to represent what that locale will be like, where the proposed facilities are allowed to be built. Potential blockage of view corridors and shadow studies are also frequently analyzed through the use of CAD.[8]
There are several different types of CAD,[9] each requiring the operator to think differently about how to use them and design their virtual components in a different manner. Virtually all of CAD tools rely on constraint concepts that are used to define geometric or non-geometric elements of a model.
There are many producers of the lower-end 2D sketching systems, including a number of free and open-source programs. These provide an approach to the drawing process where scale and placement on the drawing sheet can easily be adjusted in the final draft as required, unlike in hand drafting.
3D wireframe is an extension of 2D drafting into a three-dimensional space. Each line has to be manually inserted into the drawing. The final product has no mass properties associated with it and cannot have features directly add to it, such as holes. The operator approaches these in a similar fashion to the 2D systems, although many 3D systems allow using the wireframe model to make the final engineering drawing views.
3D "dumb" solids are created in a way analogous to manipulations of real-world objects. Basic three-dimensional geometric forms (e.g., prisms, cylinders, spheres, or rectangles) have solid volumes added or subtracted from them as if assembling or cutting real-world objects. Two-dimensional projected views can easily be generated from the models. Basic 3D solids do not usually include tools to easily allow the motion of the components, set their limits to their motion, or identify interference between components.
Top-end CAD systems offer the capability to incorporate more organic, aesthetic and ergonomic features into the designs. Freeform surface modeling is often combined with solids to allow the designer to create products that fit the human form and visual requirements as well as they interface with the machine.
Originally software for CAD systems was developed with computer languages such as Fortran, ALGOL but with the advancement of object-oriented programming methods this has radically changed. Typical modern parametric feature-based modeler and freeform surface systems are built around a number of key C modules with their own APIs. A CAD system can be seen as built up from the interaction of a graphical user interface (GUI) with NURBS geometry or boundary representation (B-rep) data via a geometric modeling kernel. A geometry constraint engine may also be employed to manage the associative relationships between geometry, such as wireframe geometry in a sketch or components in an assembly.
