Provides a wide range of tools and functionalities that aid in the design process, such as drawing and editing tools, geometric constraints, parametric modeling, assembly modeling, rendering, simulation, and analysis capabilities.

Facilitates collaboration and communication among design teams, as designs can be easily shared, reviewed, and revised.

PRIMARY PURPOSE OF CAD

Allows designers to explore multiple design alternatives, make modifications easily, and perform virtual testing and analysis to validate their designs.

When CAD began.

Father of CAD/CAM, developed PRONTO.

The first commercial numerical-control programming system.

The first numerical control (NC) systems were were developed, which used punched paper tapes to control machine tools.

Which used punched paper tapes to control machine tools.

Created the first interactive computer graphics program called __ which allowed users to create and manipulate geometric shapes using a light pen.

The first commercial computer-aided design systems began to emerge, primarily used for __ and __ design.

2D CAD systems became more prevalent, with the introduction of graphics terminals and the use of dedicated minicomputers for CAD applications.

The development of AutoCAD by Autodesk revolutionized the CAD industry.

Was one of the first widely adopted CAD software packages and helped popularize the use of personal computers for design work.

Saw the introduction of 3D CAD systems.

allowed designers to create and manipulate three-dimensional models of their designs.

One of the first commercially successful 3D CAD systems and played a significant role in popularizing 3D modeling.

Use of 3D CAD became more widespread, with the development of solid modeling techniques and improvements in computer hardware and graphics capabilities.

PLM

Brought about tighter integration between CAD and other product development processes through the concept of PLM.

Allowed for better collaboration, data management, and automation of design processes, connecting CAD with other disciplines like simulation, analysis, and manufacturing.

Became widely used, enabling designers to create relationships between model features and easily modify designs by changing parameters.

CAD has seen advancements in cloud-based CAD tools, which allow for easier collaboration, access from anywhere, and improved scalability.

Have gained popularity, enabling designers to work on their smartphones and tablets.

Are being incorporated into CAD systems, offering automated design optimization, generative design, and intelligent assistance to designers.

Has evolved significantly over time, from its early origins as a tool for __ to its current state as an integral part of the product development process, facilitating faster and more efficient design iterations.

CAD tools provide precise measurements, alignment, and geometric constraints, minimizing errors and ensuring accurate designs.

CAD software offers realistic 2D and 3D visualization, allowing designers to view and present their designs from different angles, enhancing communication and understanding.

CAD facilitates exploring multiple design alternatives and making modifications easily enabling designers to evaluate different options and optimize their designs.

CAD systems supports, allowing designers to establish relationships between design features and parameters.

Enables quick design changes by automatically updating associated components.

Enables designers to test and evaluate designs virtually for factors such as stress, performance, fluid dynamics, and thermal behavior.

Enables seamless collaboration among design teams, as designs can be easily shared, reviewed, and revised, leading to improved teamwork and efficiency.

Can be expensive, especially for professional-grade packages, which may require additional training and licensing fees.

However, there are also free and open-source CAD software options available.

Becoming proficient in CAD software may require some learning and practice.

Complexity of certain CAD tools can initially pose a challenge for new users.

CAD software can demand powerful hardware to run efficiently, including high-performance computers with adequate processing power, memory, and graphics capabilities.

CAD software may undergo frequent updates, requiring users to stay updated and ensure compatibility with other software, file formats, and operating systems.

CAD software focuses on digital modeling which may lead to less emphasis on physical prototypes and hands-on experience, potentially limiting the tactile understanding of the design.

Sharing CAD files between different software platforms can sometimes lead to compatibility issues, requiring file conversions or adjustments.

While CAD software enhances productivity and efficiency, it may result in reduced manual drafting skils and a dependence on the software for certain design tasks.
