CAD/CAM/CAE

WHAT IS CAD?

Computer-aided design (CAD) is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD part is used in almost all the branches of engineering but CAM technology is specially used in Mechanical/Automobile/ Aeronautic/Electrical/Electronics/Civil/ Production engineering.

CATIA (Computer Aided Three-dimensional Interactive Application)

CATIA (Computer Aided Three-dimensional Interactive Application) is a multi-platform CAD/CAM/CAE commercial software suite developed by the French company Dassault Systèmes directed by Bernard Charlès. Written in the C++ programming language, CATIA is the cornerstone of the Dassault Systèmes software suite. CATIA, developed by Dassault Systems, is one of the world’s leading CAD/CAM/CAE packages. Being a solid modeling tool, it not only unites the 3D parametric features with 2D tools, but also addresses every design-through-manufacturing process. Besides providing an insight into the design content, the package promotes collaboration between companies and provides them an edge over their competitors. In addition to creating solid models, sheet metal components, and assemblies, 2D drawing views can also be generated in the Drafting workbench of CATIA. The drawing views that can be generated include orthographic, section, auxiliary, isometric, and detail views. You can also generate model dimensions and create reference dimensions in the drawing views. The bi-directionally associative nature of this software ensures that the modifications made in the model are reflected in the drawing views and vice versa.

Part Design Workbench

The Part Design workbench is a parametric and feature-based environment in which you can create solid models. The basic requirement for creating a solid model in this workbench is sketch. The sketch for the features is drawn in the Sketcher workbench that can be invoked within the Part Design workbench. You can draw the sketch using the tools in this workbench. While drawing the sketch, some constraints are automatically applied to it. You can also apply additional constraints and dimensions manually. After drawing the sketch, exit the Sketcher workbench and convert it into a feature. The tools in the Part Design workbench can be used to convert the sketch into a sketch-based feature. This workbench also provides other tools to apply the placed features, such as fillets, chamfers, and so on. These features are called the dress-up features. You can also assign materials to the model in this workbench.

Wireframe and Surface Design Workbench

The Wireframe and Surface Design workbench is also a parametric and feature-based environment, and is used to create wireframe or surface models.

Assembly Design Workbench

The Assembly Design workbench is used to assemble the components using the assembly constraints available in this workbench. There are two types of assembly design approaches: 1. Bottom-up 2. Top-down In the bottom-up approach of the assembly design, the components are assembled together to maintain their design intent. In the top-down approach, components are created inside the assembly in the Assembly Design workbench. You can also assemble an existing assembly to the current assembly. The Space Analysis toolbar provides the Clash analysis tool that helps in detecting clash, clearance, and contact between components and subassemblies.

Drafting Workbench

The Drafting workbench is used for the documentation of the parts or assemblies created earlier in the form of drawing views and their detailing. There are two types of drafting techniques: 1. Generative drafting 2. Interactive drafting The generative drafting technique is used to automatically generate the drawing views of the parts and assemblies. The parametric dimensions added to the component in the Part Design workbench during its creation can be generated and displayed automatically in the drawing views. The generative drafting is bidirectional associative in nature. You can also generate the Bill of Material (BOM) and balloons in the drawing views. In interactive drafting, you need to create the drawing views by sketching them using the normal sketching tools and then adding the dimensions.

Generative Sheetmetal Design

Workbench The Generative Sheetmetal Design workbench is used for the designing of the sheet metal components. Generally, the solid models of the sheet metal components are created to generate the flat pattern of the sheet, study the design of the dies and punches, and study the process plan for designing. This workbench also provides the tools needed for manufacturing the sheet metal components.

DMU Kinematics Workbench

The DMU Kinematics workbench is used to design mechanisms by adding joints between the components. It also allows you to simulate and analyze the working of the mechanisms dynamically.

FreeStyle Workbench

The FreeStyle workbench is used to manipulate and refine an existing surface. In addition, you can create independent surfaces and analyze the surfaces using the tools available in this workbench.
