What is CAD & how does it work?

Computer-Aided Design ( CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing.

Why do engineers use CAD software?

CAD enables the development, modification, and optimization of the design process. Engineers can make more accurate representations and modify them easily to improve design quality. The software also takes into account how various materials interact: This is especially relevant as more details are added to drawings by subcontractors.

What are the different types of CAD simulation and analysis tools?

A common CAD simulation and analysis tool is finite element analysis (FEA). This is illustrates how parts and assemblies behave when dynamically loaded. Examples include stress, strain, structural and vibration testing. Another related field of analysis and simulation is computational fluid dynamics (CFD) for examination of fluid flow.

What are the intelligent features of CAD?

Other intelligent features include sustainability, energy and carbon footprint impact of CAD models, based on material choices. Alternative intelligent CAD attributes include design for manufacture (DFM) rules and ergonomic guidelines, both of which validate designs at the digital stage. Next...
