SOLID WORK
SolidWorks is a 3D mechanical CAD (computer-aided design) program that runs on Microsoft Windows and was developed by SolidWorks Corporation - now a subsidiary of Dassault Systèmes, S. A. (Suresnes, France). SolidWorks is a parametric feature-based solid modeler, using the Parasolid geometric modeling kernel. SolidWorks was introduced in 1995 as a competitor to CAD programs such as Pro/ENGINEER, I-DEAS, Unigraphics, CATIA, and Autodesk Mechanical Desktop, and is currently one of the leading products in the "midrange" or "mainstream" mechanical CAD marketSolidWorks employs a parametric, feature-based approach to creating models and assemblies. Parameters refer to constraints or conditions whose values determine the size, shape, characteristics, and behavior of the model or assembly. Parameters can be either numeric, for example dimension values such as the diameter of a circle or the length of a line; or geometric, such as conditions like tangent, concentric, coincident, parallel, horizontal, and the like. Numeric parameters such as dimensions can easily be related to each other through equations to capture even the most complicated design intent.Features refer to the building blocks of the part. They are the shapes and operations that construct the part. Shape-based features would include slots, holes, bosses and the like that either add or remove material from the part. Shape-based features typically begin with either a 2D or 3D sketch. Operation-based features generally don’t have sketches. These types of features include operations like filleting, chamfering, shelling, or applying draft to a part.
