Siemens PLM Software releases Version 66.0 of the D-Cubed 2D DCM.
2D DCM enhancements include 1) handling of over-constrained but consistent models in the presence of equations, 2) a new autoconstraining option, and 3) additional circle solving information.
1. Enhancement: Linear Equations and Over-constrained but Consistent Models
2D DCM has the ability to solve over-constrained but consistent models. These models have more than the minimum number of constraints required but the constraints are all consistent with each other.
2D DCM is also able to couple the relative values of dimensions using equations. Previously, equations could possibly combine with consistent constraints to over-define a model. This release enables linear equations and over-constrained but consistent constraints to co-exist without over-defining a model.
2. Enhancement: Maximum Constraints when Autoconstraining
2D DCM offers various methods and options for automatically identifying dimensions and constraints. One method enables constraints to be efficiently identified without accounting for current dimensions and constraints. This method is extended in version 66 to provide an option to identify the maximum number of potential constraints of the specified types.
3. Enhancement: Circle Inversion
Normal 2D DCM behaviour is to prevent an algebraic solution from jumping from one form of solution to another. For example, a circular arc will not invert and change from being convex to concave. However, on occasion, such behaviour is desirable, and the application can instruct the 2D DCM to permit such changes when solving the model.
The latest release of 2D DCM provides additional information to the application to more comprehensively enable a circle inversion to be identified and acted upon by relevant changes to other geometries.
About D-Cubed 2D DCM
First released in 1990, D-Cubed 2D Dimensional Constraint Manager (2D DCM) is used in many major CAD applications and is widely acknowledged as the leading 2D geometric constraint solver. In addition to driving the sketcher in most mechanical CAD products, 2D DCM is used in many CAM and CAE applications.
