How CAD is used in engineering?

CAD is mainly used for detailed design of 3D models or 2D drawings of physical components, but it is also used throughout the engineering process from conceptual design and layout of products, through strength and dynamic analysis of assemblies to definition of manufacturing methods of components.

What is 3D CAD?

Other 3D CAD-based analysis and simulation techniques includes plastic injection mould flow and fatigue testing. CAD models are increasingly intelligent, where features and attributes can be attached to components and assemblies you design. This data can then be used to enhance testing or product development further downstream.

What is a CAD file?

CAD files often depict proposed infrastructure assets, or other proposed changes to the build or natural environment that can be represented on a map in their geographic context. The CAD drawings are often a source of new infrastructure assets, or changes to the natural environment and can be used to create or update GIS datasets.

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.
