CAD vs CADD: Difference and Comparison

Key Takeaways

1. Full Form: CAD stands for Computer-Aided Design. CADD stands for Computer-Aided Design and Drafting.
2. Scope: CAD refers specifically to designing products and components using computer software. CADD encompasses CAD along with the drafting and documentation process.
3. Usage: CAD is used mainly by engineers and designers for creating 3D models and designs. CADD refers to the broader workflow of CAD design and 2D technical drawings done by drafters and technicians.

What is CAD?

CAD stands for Computer-Aided Design. It refers to the use of computer software to create, modify, analyze, and optimize designs for various industries such as architecture, engineering, manufacturing, and product development.

CAD software allows designers and engineers to create precise, detailed, and accurate digital models of objects or systems. These models can range from simple 2D drawings to complex 3D representations. CAD tools provide a wide range of features and functionality to support the design process.

What is CADD?

CADD stands for Computer-Aided Design and Drafting. It is a term used to describe the combination of computer-aided design (CAD) and computer-aided drafting (CAD) technologies. CADD encompasses the use of computer software and tools to create, modify, and document designs, primarily in the fields of architecture, engineering, and construction.

While CAD focuses on creating and modifying digital models and designs, CADD extends this functionality to include drafting capabilities. Drafting refers to the creation of technical drawings, plans, and diagrams that convey design information in a standardized format.

Difference Between CAD and CADD

1. CAD (Computer-Aided Design) refers specifically to the use of computer software for creating, modifying, and analyzing designs. It focuses on the design aspect of the process, encompassing 2D and 3D modelling. On the other hand, CADD (Computer-Aided Design and Drafting) includes CAD functionality but extends it to include drafting capabilities, such as the creation of technical drawings, plans, and diagrams.
2. CAD primarily focuses on creating and modifying digital models, allowing designers to visualize and analyze their designs in a virtual environment. It emphasizes the modelling and design aspects. In contrast, CADD includes drafting tools and functionality, enabling designers to create precise and detailed technical drawings that adhere to industry standards. It emphasizes the documentation and communication of design intent.
3. CAD software offers a wide range of tools and features for modelling, simulation, analysis, and visualization of designs. It provides advanced capabilities for creating complex 2D and 3D models. CADD extends CAD functionality by incorporating drafting tools like annotation, dimensioning, and symbol libraries. These tools facilitate the creation of technical drawings and enable the inclusion of important information and specifications.
4. CAD primarily focuses on generating digital design models, which can be used for visualization, analysis, and simulation purposes. The output in CAD is in the form of digital files, such as 3D models or renderings. On the other hand, CADD emphasises the creation of standardized technical drawings and plans as output. These drawings are used for communication, documentation, and construction purposes.
5. CAD is widely used in various industries, such as architecture, engineering, manufacturing, and product design. It caters to the needs of designers and engineers who focus on the modelling and visualization of designs. CADD is commonly used in industries that require both design and drafting capabilities, such as architecture, civil engineering, mechanical engineering, and construction. It serves the needs of professionals involved in a project’s design and documentation aspects.
