What is 3D CAD Modelling?

To start with, CAD stands for Computer-Aided Design. It finds its applications in a wide range of industries – Architecture, Animations, Mechanical and Electronic Designers, Manufacturing and the list goes on. It is of 2D and 3D CAD.

3D CAD is a part of Virtual Product Development/Digital Product development process in the product life cycle and management and followed by- 

  • Computer-Aided Engineering – Structural,
  • Thermal and Fluid Analyses (FEA and CFD)
  • Computer-Aided Manufacturing (CAM)
  • Photo Realistic Rendering
  • Documentation and PDM

3D CAD allows to model components/parts as the three-dimensional virtual object as in the real world with its actual properties – mass, appearance, material etc. This is not limited to simple and prism shapes, any complex shaped solids and surfaces can be designed and generated.

3D modelling, not only allows us to create parts/components and also allows us to assemble them with the same physical behaviour of the mechanism.

3D CAD can be subdivided as follows

  • Solid Modelling
  • Surface Modelling
  • Wireframe modelling

Why 3D CAD modelling?

  • 3D modelling helps to get into the perspective of ‘How the product would look in real-time before manufacturing’
  • It gives you a better understanding of the product size, shape, bounding box and packaging
  • It is precise and accurate – enables to quantify the sizing, clearances and fit in the assembly with ease
  • It helps to make the product cost-effective and market in time
  • Assemblies and Mechanism can be validated, simplified and enhanced easily
  • Before prototyping, mechanicals, fitments, spacing and cosmetics errors can be easily identified and rectified
  • Cross-section view, exploded view, illustrations, SOP, DFMA can be performed
  • It is effective and efficient to deliver the product 45% faster than the conventional methodologies
  • Improves product development cycle communication, reduces errors and cycle time
  • It documents the components with manufacturing drawings, Bill of materials, and Material requirements.
