What is CAD & how does it work?

CAD is used to create precise drawings and models of objects and structures, either in 2D or 3D. CAD was developed as a more accurate, affordable way for designers, engineers and manufacturers to design, visualize and test models while minimizing the chance of mistakes.

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.

Why do architects use CAD?

Architecture is heavily reliant on the creation of complex yet highly accurate drawings and models, so CAD is an invaluable tool to architects. CAD is also useful to architects as certain software, like Revit and ArchiCAD, use BIM workflows to improve productivity.

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.
