It developed the world's first 3D CAD application that ran on a desktop PC. SolidWorks released its first product, SolidWorks 95, on November 1, 1995. The 3D CAD product, now known as SolidWorks,

94-558: A CAD program vendor. Constraints are widely employed in CAD software for solid modeling , computer-aided architectural design such as building information modeling , computer-aided engineering , assembly modeling, and other CAD subfields . Constraints are usually used for the creation of 3D assemblies and multibody systems . A constraint may be specified for two or more entities at once. For instance, two lines may be constrained to have equal length or diameter of circles can be set to have

141-416: A CAD system that maintained this structure as a designer manipulated geometric model. In the 1970s the idea was further extended into three-dimensional space . In the 80s, a more generalized constraint-based programming language approach emerged and found some application in CAD software. At least one conceptual prototype was built in 1989. The purpose of constraints in a design is to control and limit

In 1999, the SolidWorks brand started introducing solutions complementary to 3D modeling and in 2006 introduced SolidWorks Design-to-Manufacturing solutions, an integrated system enabling design and manufacturing teams to work together concurrently. As

235-526: A design intent, varying geometry, family tables, or as driving dimensions. In assembly modeling, constraints are widely used to control or restrict design parts movements or relationships between each other. Some constraints forces models to respond to changes made in a separate part of a designed product. This enables the design to be responsive as a whole. Implementation of constraints functionality vary with given CAD system and may respond differently to how user applies them. When constraints are added into

282-511: A design model (i.e. sketch) that maintains its structure as the model is manipulated. These properties can include relative length, angle, orientation, size, shift, and displacement. The plural form constraints refers to demarcations of geometrical characteristics between two or more entities or solid modeling bodies; these delimiters are definitive for properties of theoretical physical position and motion, or displacement in parametric design . The exact terminology, however, may vary depending on

611-452: A sketch some system may be smart enough to apply additional ones based on pre-existing entities automatically. For instance, if the line is drawn next to another one the system may figure to constrain them into being in parallel relative to each other. This sometimes, however, may lead to unexpected results. Constraint solver is a dedicated software that calculates positions of points of the 2D sketch based on geometric constraint specified by

658-586: A time-consuming process. One approach to this situation may be referred as removing degrees of freedom (DOF). The latter are often represented by (X,Y,Z) coordinates in space. The designer may quickly figure out whether an entity is constrained or not by counting the number of DOFs removed from it. There are several constraints that may be applied between entities or bodies depending on their actual natural geometry (may also be referred to as ’’mates’’): collinearity , perpendicularity , tangency , symmetry , coincidency, and parallelism are ways of establishing

1034-514: The Parasolid modeling 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

1081-444: The same dimension (e.g., radius or length). Moreover, the constraint may be applied to solid models to be locked or fixed in a specified space. Concept of constraints is applicable for both two- (2D) three-dimensional (3D) sketches (including the ones used to create extrusions and solid bodies). The concept of constraints initially emerged in the 1960s and were further developed in the 1970-80s. The original idea of "constraints"

Examples of this strategy include

1316-414: The behavior of the entities and bodies in relation to another entity, plane or body. Effective constraints or mates between two or more bodies may exist at the assembly level of these or between two or more entities in defining a sketch, but adding conflicting, unnecessary or redundant constraints may result in an overdefined sketch and an error message. Development of a good constraining system might be

1363-407: 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 to add or cut to 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
