AutoCAD deals with the designing of software that is used to create digital designs of structures. It implicates the study of the technicalities, applications, and other characteristics of computer-aided design to construction drawings and models for engineers, designers, and architects. The average duration of AutoCAD courses can range from 1 to 6 months.
CATIA is the reduced form of Computer Aided Three-Dimensional Interactive Application developed by French company Dassault Systemes and marketed worldwide by IBM. It is a complete multi-platform solution for Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM), Computer-Aided Engineering (CAE), PLM and 3D.
CATIA is a product design software, which is ideal for surfaces, creating solids, drawings, assemblies, fabrication and analysis. This software is used in multiple industries like in manufacturing industries, automobile, aerospace, etc. to visualize designs in 3D. These industries use CATIA to model any product, to integrate 3D features with 2D tools and to develop 2D drawing views.
Pro/ENGINEER is a parametric, integrated 3D CAD/CAM/CAE solution created by Parametric Technology Corporation . It was the first to market with parametric, feature-based, associative solid modeling software. The application runs on Microsoft Windows platform, and provides solid modeling, assembly modelling and drafting, finite element analysis, Direct and Parametric modelling, Sub-divisional and nurbs surfacing and NC and tooling functionality for mechanical engineers.
Pro offers a range of tools to enable the generation of a complete digital representation of the product being designed. In addition to the general geometry tools there is also the ability to generate geometry of other integrated design disciplines such as industrial and standard pipe work and complete wiring definitions. Tools are also available to support collaborative development.A number of concept design tools that provide up-front Industrial Design concepts can then be used in the downstream process of engineering the product. These range from conceptual Industrial design sketches, reverse engineering with point cloud data and comprehensive free-form surface tools.
