The success of our customers is also our success: we are constantly working to satisfy their requirements and improve our technology.

Bricsys, a global provider of dwg engineering design software brought to market under the BricsCAD® brand, today released V9 of LGS component technology, a set of computational software libraries used by developers of CAD, CAM, CAE applications for implementation of geometric and dimensional constraint support.

This is the third release of this mature software since the acquisition of the corresponding intellectual property rights from LEDAS in 2011. Both LGS 2D and LGS 3D libraries were integrated in BricsCAD V12 to support parametric drawing and variational direct modeling. Later the areas of application of LGS were extended to assembly design in BricsCAD V13, and sheet metal design in BricsCAD V14. Now it is a powerful constraint solving technology, which proved its ability to solve complex industrial parametric models created by thousands of BricsCAD customers.

Version 9.0 makes a significant breakthrough in constraint solving techniques, which aim at finding the most natural (most expected by the end user) solution for a constraint problem. It also contains several improvements and fixes related to different problems reported by the customers.

In particular LGS 2D 9.0 provides better diagnostics for geometric objects and constraints.
It also contains a new reliable method of solving coincidence constraint between two lines.

LGS 3D 9.0 allows users to edit 3D sheet metal models very smoothly and efficiently. It also implements special methods to minimize the number of transformed geometries, when it is possible. With LGS 3D 9.0 it is possible to control the distance between the closest points of two circles lying on parallel planes.

“LGS technology is available for licensing to all software developers with no relation to BricsCAD,” explained Erik De Keyser, CEO Bricsys. “Sometimes our licensees use LGS technology more extensively than we do in BricsCAD. A good example gives CEAD software developed by CADVision Engineers for constraint-driven engineering design synthesis. The success of our customers is also our success: we are constantly working to satisfy their requirements and improve our technology.”

About LGS Component Technology
LGS 2D and 3D variational constraint solvers are state-of-the-art computational engines aimed to help developers of engineering software to implement advanced parametric functions in their applications. Users of these applications can rely on geometric and dimensional constraints, which are solved simultaneously forcing the change of geometry according to design intent.

LGS 2D and 3D are available as binary libraries for Windows, Mac OS X, and Linux platforms. The C Application Programming Interface allows easy integration of LGS 2D/3D into applications written in C/C++/C#/Java and many other programming languages.
