SolidWorks is solid modelling software that allows you to design products in 3 dimensions. The technique is generally to sketch 2D profiles then use methods like extruding and lofting to produce the solid shape. Here are some examples:To model a paperclip, sketch the profile then sweep the wire diameter along it.
SolidWorks is a 3D mechanical CAD (computer-aided design) program that runs on Microsoft Windows. SolidWorks files use the Microsoft Structured storage file format. This means that there is various files embedded within each SLDDRW (drawing files), SLDPRT (part files), SLDASM (assembly files), with preview bitmaps and metadata sub-files. Various third-party tools can be used to extract these sub-files, although the sub-files in many cases use proprietary binary file formats. SolidWorks is a parasolid-based solid modeller, and utilizes a parametric feature-based approach to create models and assemblies. Parameters refer to restrictions which values determine the shape or geometry of the model. Parameters can be either numeric, such as line lengths or circle diameters, or geometric, such as tangent, parallel, concentric, horizontal or vertical. Numeric parameters can be associated with each other through the use of relations, which allows them to capture design intent.
