Learn SolidWorks 2D 3D Manual is a solid modeler and utilizes a parametric feature-based approach to create models and assemblies. The software is written on Parasolid-kernel.Parameters refer to constraints whose values determine the shape or geometry of the model or assembly. Parameters can be either numeric parameters such as line lengths or circle diameters or geometric parameters such as tangent parallel concentric horizontal or vertical etc. Numeric parameters can be associated with each other through the use of relations which allows them to capture design intent.

Design intent is how the creator of the part wants it to respond to changes and updates. For example you would want the hole at the top of a beverage can to stay at the top surface regardless of the height or size of the can. SolidWorks allows the user to specify that the hole is a feature on the top surface and will then honor their design intent no matter what height they later assign to the can.

Features refer to the building blocks of the part. They are the shapes and operations that construct the part. Shape-based features typically begin with a 2D or 3D sketch of shapes such as bosses holes slots etc. This shape is then extruded or cut to add or remove material from the part. Operation-based features are not sketch-based and include features such as fillets chamfers shells applying draft to the faces of a part etc. Thanks for download Learn SolidWorks 2D 3D Manual
