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). It is currently one of the most popular products in the "midrange" or "mainstream" mechanical CAD market.[1]

[edit] History

SolidWorks was introduced in 1995 as a low-cost competitor to CAD programs such as Pro/ENGINEER, SDRC I-DEAS, Unigraphics, AutoCAD and CATIA. SolidWorks Corporation was founded in 1993 by Jon Hirschtick, with its headquarters at Concord, Massachusetts, and released its first product, SolidWorks 95, in 1995. In 1997 Dassault Systèmes, best known for its CATIA CAD software, acquired the company and currently owns 100% of its shares. SolidWorks was headed by John McEleney from 2001 to July, 2007, and is now headed by Jeff Ray, CEO.

[edit] Market

Solidworks is used by product designers and mechanical engineers worldwide. Its user base ranges from individuals to large companies, and covers a very wide cross-section of manufacturing market segments. Commercial sales are made through an indirect channel, which includes dealers and partners throughout the world. Directly competitive products to SolidWorks include Pro/ENGINEER, Solid Edge, and Inventor.

[edit] The SolidWorks Approach

SolidWorks is a parasolid-based solid modeler, and utilizes a parametric feature-based approach to creating models and assemblies.

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.

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 fillets, chamfers, shells, applying draft to the faces of a part, etc.

Building a model in SolidWorks usually starts with either a 2D or 3D sketch. The sketch consists of geometry such as lines, arcs, conics, and splines. Dimensions are added to the sketch to define the size and location of the geometry. Relations are used to define attributes such as tangency, parallelism, perpendicularity, concentricity, and such. The parametric nature of SolidWorks means that the dimensions and relations drive the geometry, not the other way around. The dimensions in the sketch can be controlled independently, or by relationships to other parameters inside or outside of the sketch.

As with all feature-based solid modeling software, SolidWorks allows the user to roll back through the history of the part in order to make changes, add additional features, or change to sequence in which operations are performed.

In an assembly, the analog to sketch relations are mates. Just as sketch relations define conditions such as tangency, parallelism, and concentricity with respect to sketch geometry, assembly mates define equivalent relations with respect to the individual parts or components, allowing the easy construction of assemblies. SolidWorks also includes additional advanced mating features such as gear and cam follower mates, which allow modeled gear assemblies to accurately reproduce the rotational movement of an actual gear train.

Finally, drawings can be created either from parts or assemblies. Views are automatically generated from the solid model, and notes, dimensions and tolerances can then be easily added to the drawing as needed. The drawing module includes most paper sizes and standards (ANSI, ISO, DIN, GOST, JIS, BSI and GB).

[edit] Add-in Products

SolidWorks allows for the seamless integration of third-party modules. Some of these modules are small and introduce a minor feature, such as generating a special shaped hole, while others are entire Computer Aided Manufacture products in their own right that use SolidWorks as a convenient graphical platform.

These products can apply for different levels of partner status with the SolidWorks company, to give the advantage of being promoted through the established SolidWorks sales channels. See Partner Products

[edit] Other modules

[edit] COSMOSFloWorks

COSMOSFloWorks is a Computational Fluid Dynamics (CFD) product for SolidWorks users. It is embedded inside SolidWorks and can perform fluid flow and heat transfer analysis for all types of fluids (liquids, gases, Non Newtonian liquids, Compressible liquids).

The solver uses Navier-Stokes (NS) equations to compute flow characteristics in both Single Reference Frames (SRF) and Multiple Reference Frames (MRF).

[edit] COSMOSMotion

COSMOSMotion is a SolidWorks module for multi-body kinematic simulation of mechanisms. It can handle complex component collisions, accept formula for motion laws and supply reaction values to COSMOSWorks for further FEA analysis. It is included in the SolidWorks Premium license.

[edit] COSMOSXpress

COSMOSXpress is a feature designed to perform a very limited range of linear static analysis of part geometry. Geometry is limited to a single solid body and the choices for creating boundary conditions are extremely limited which can affect the applicability of the results to the actual problem being solved. Results are limited to a graphical representation of Von Mises stress and deformed shape although actual displacements are not available. COSMOSXpress is included in the very basic SolidWorks license, but is considered superseded by COSMOSWorks Designer (included in SolidWorks Premium).

[edit] COSMOSWorks Designer

COSMOSWorks Designer is a module providing a richer set of tools for linear static FEA. COSMOSWorks Designer can deal with parts and assemblies using solid, shell and (starting from release 2007) beam elements.

It provides a fully associative environment to perform FEA studies inside SolidWorks, with several features for pre-processing as well as for post-processing and a very rich set of connectors and boundary conditions, like virtual bolts, bearings, spot welding, links and pins.

A tool for designing multiple batch calculations (Design Scenario) is also provided.

COSMOSWorks Designer can handle locally non-linear contact and includes a partial support for geometric non-linear analysis (large displacement). It is included in the SolidWorks Premium license.

[edit] COSMOSWorks Professional and Advanced Professional

COSMOSWorks license upgrades including a larger set of solvers.

COSMOSWorks Professional:

  • Buckling
  • Frequency
  • Thermal
  • Fatigue
  • "Drop test"
  • Shape optimization

COSMOSWorks Advanced Professional:

  • all of the above, plus:
  • Composite analysis
  • Seismic
  • Post-dynamics
  • Complete non-linear analysis

[edit] PhotoWorks

PhotoWorks is a raytrace renderer built into SolidWorks, powered by Mental Ray

[edit] Toolbox

SolidWorks Toolbox is a library of predefined fasteners, gears, cams, pins and other accessories, based on information found in Machinery's Handbook. The library is database driven and this database can be modified. Also user defined standard parts can be created and added to the Toolbox for later use in other projects.

SolidWorks Toolbox allows for "drag and drop" insertion of fasteners into assemblies. It also is integrated with SolidWorks "SmartFastener" technology to allow the automatic population of hole features with the appropriate fasteners.

[edit] Motion Study (previously called Animator)

SolidWorks Animator has the capability of exploding assemblies and animates the way components explode, join.

It relies on standard SolidWorks kinematics, but can also accept motion simulation results from COSMOSMotion, as well as a thorough manipulation by the user.

It can also produce video output and supports rendered animations using PhotoWorks.

[edit] FeatureWorks

This module recognizes different design features (fillets, cut-extrudes, extrudes) on imported models. The underlying methods for the recognition of different features in the dumb solid are mainly identified as Feature Recognition technologies in the CAD/CAM industry.

[edit] ScanTo3D

Module to perform Reverse engineering, starting from point-cloud or STL/VRML files, as well as using 3D scanning. Included in SolidWorks Premium, starting from release 2007.

[edit] API

SolidWorks also includes an Application Programming Interface (API) for macro and third party development.

[edit] File format

SolidWorks files use the Microsoft Structured storage file format. This means that there are various files embedded within each SLDDRW, SLDPRT, SLDASM file, including preview bitmaps and metadata sub-files. Various third-party tools (see Structured storage) can be used to extract these sub-files, although the subfiles in many cases use proprietary binary file formats.
