Current version is LGS 2D 2.0

The LEDAS Company opens new direction of geometric solvers development with release LGS 2D 2.0.

The main new feature of the recently released version 2.0 is its capability to deal with discrete entities in a geometric model. The difference between real-life engineering and pure math problems is that real designs often contain parts and elements of standardized sizes or sets of predefined mechanisms configurations and models. Describing these problems with the help of continuous entities, has always been a drawback of geometric modeling.

Now any licensee of LGS 2D 2.0 has capability to specify the table constraint which lists all possible combinations of values of different variables in the model and ensures that LGS 2D selects one of these configurations during computations, providing a user with a solution consistent from engineer point of view. In order to limit a particular variable by a set of all possible values, one can use more simple enumeration feature. For more details see clip about table constraints.

Besides, the success rate and naturality of LGS solutions has been increased. A number of bugs, including the lack of unfixed parameter support for Vertical and Horizontal Distance constraints, are fixed.

For the full list of changes see Release Status page.

About LGS 2D

The LGS 2D geometric solver is a computational module engineered to support two-dimensional parametric design in CAD and computer graphics systems, as well as many other applications that require parametric connections or constraints to be set between geometrical objects. LGS 2D incorporates the latest technologies in programming, computational mathematics and computer algebra, and is based on a highly efficient kernel. This stability and performance in turn allows additional powerful functions related to geometrical objects constraints to be built upon the kernel and supported in a wide range of systems.

Following the merger of the CAD giant UGS PLM Solutions and the English company D-Cubed, a well known producer of DCM solvers, and, LEDAS remains the only independent supplier of competitive parametric design solvers worldwide.

Parametric design is present in many modern CAD systems. High-end CAD systems have for years incorporated parametric design in drawing modules, while recently small and medium class CAD programs have also recognized its value. Additionally, the fundamental precepts of parametric design open up a wide range of possibilities for the CAD user to impose constraints on geometric objects and incorporate them into a wide range of applications. Consider graphic editing programs. From the simplest vector editors to highly sophisticated two dimensional modeling packets, implementing an array of constrained variables in place of rigidly connected image elements can greatly simplify the designer's work. This is equally true during both the creation and editing periods.

Further, accounting for geometric constraints has demonstrated utility in certain visualization systems where data exchange between vector applications takes place. Possible examples include the interactive systems in automobiles or in the real-estate trade market.
