LEDAS Releases LGS 2D v5 Constraint Solver with Extended Functions

By DE Editors

LEDAS Ltd. has announced version 5.0 of LGS 2D, its geometric constraint solver. It allows users to express design intent in their sketches and drawings through geometric and dimensional constraints.

Version 5.0 extends the functionality of pattern constraints that were introduced in the previous version of LGS 2D. New are circular and variable patterns, as well as distance constraints for ellipses.

Linear variable patterns extend ordinary linear patterns introduced in the previous version of LGS 2D. They link the distance between centers of any two adjacent objects with variables, allowing non-uniform distribution along a given direction, fully controlled through variables. The lengths of all the intervals not linked to variables are made uniform by the solver.

Circular patterns are applied to sets of objects of the same type. Another argument is the point, around which LGS 2D distributes the objects. The distance between the point and each object is equal, as are the angles between adjacent rays (that connect the point with objects’ centers).

Circular variable patterns, similarly to linear variable patter, use variables to control the angles between adjacent rays.

The directed distance constraint was firstly implemented in LGS 2D; in v5, ellipses can be used as arguments to this kind of constraint. Now any object (except lines, for which directed distances do not make sense) can be constrained with this type of constraint, according to the company.

“Version 5.0 finalizes the new family of functions introduced with the previous version, following requests from our customers,” says Dmitry Ushakov, director of Product Management at LEDAS.
