The Course training in designing actually covers computer based designing of structures, shapes, profiles and variety of asymmetric / symmetrical objects & structures - small or big, with sharp and precise forms either in 2D or 3D, before they are actually made using the specified material. This kind of designing enables ease in manufacturing the objects by saving much time and energy and at unbelievably lesser costs when mass production of them is considered.
A larger part in design course is AutoCAD, which is a software application for 2D & 3D aided design (CAD). Before AutoCAD was introduced, most of these CAD programs ran on mainframe computers or mini-computers.
Parametric, integrated 3D CAD/CAM/CAE solution is Pro-Engineer (Pro-E) which is currently called as PTC Creo. It is a solid modeling software which is associative, feature based and parametric. ProE is a Multi-Programs software used for design, analysis and manufacturing. It deals with model creation and assemblage of designs.
The other program in Course design is Creo which is a family or group of design software which aids product design. The group consists of different apps, each having a different set of executable capabilities to be used in product development. The third program in Design is SOLIDWORKS, which is solid modeling CAD & CAE software. Solid Works is a solid modeler, and utilizes a parametric feature - based approach to create models and assemblies.
