New LEDAS strategy aims at providing ready-to-integrate toolkits of computational software modules for developers of commercial CAD/CAM/CAE applications. Having analyzed the experience of our customers in development of applications based on our geometric constraint solver LGS, we are now working on creation of a set of toolkits (software components), which can be used for rapid development of advanced variational design applications.

isicad-2008 International Forum "ERP+PLM: Informational Environment of a Modern Enterprise" will take place on 4-6 June (Wednesday-Friday) in Akademgorodok (the Academic town) of Novosibirsk and its picturesque outskirts.

LEDAS Geometric Solver (LGS) is a family of software components typically used as a computational engine for parametric design systems. Currently, two versions of the solver are offered: 2D and 3D. LGS 2D is widely used in the development of two-dimensional drafting and sketching applications, vector graphics systems and geometric data exchange tools. LGS 3D, on the other hand, supports three-dimensional, feature-based parametric design of parts and assemblies, in addition to kinematics modeling.

Flash-LGS - an online technology demonstrator of LGS computational engine for parametric design systems. The on-line demonstrator has simple intuitive user interface and provides an interactive access to functionality of LGS 2D solver, which is widely used in the development of two-dimensional drafting and sketching applications, vector graphics systems and geometric data exchange tools. Flash-LGS purpose is to show flexibility and affordability of LGS parametric computational engine in wide sense: from simplicity of solver incorporation into your applications and efficiency running them on wide range of hardware to LEDAS openness for collaboration with wide range of graphics software developers, product vendors, research and educational organizations.

The educational and training program of LEDAS is oriented to the domain of CAD/PLM/ERP and centered on applied education. The program provides: organization of theoretical and practical courses for bachelor and master degree students, trainings on application and development of CAD/PLM/ERP, commercial courses, organization of workshops, LEDAS Internships, course material publication, and others. The first four LEDAS courses are: Introduction to the Mathematical Background of CAD/CAM/CAE/PLM, Practical Programming for CAD, Technology of Science-intensive Industrial Programming, and Introduction to Information Environment of Modern Industrial Enterprise.

Building upon our foundations of scientific research in the constraint programming field, deep knowledge of modern computational algorithms, as well as rich experience in developing various software systems, LEDAS is advancing three main technologies with the provisional names, "Intervals", "Geometry" and "Scheduling".

On June 22, 1999 LEDAS Ltd. and Dassault Systemes (DS) signed a Cooperation Agreement based on the previous three years of cooperation history between DS and the Russian Research Institute of Artificial Intelligence. The cooperation between two companies is organized as a series of contracts (supplements) aimed at integrating the LEDAS solutions into CATIA Version 5 software. The supplements included development and maintenance of a powerful mathematical constraint solver, implementing end-user solutions based on this solver, extension of the user shells functionality according to the needs of DS customers, and research projects intended to prepare future constraint-based industrial solutions. Since 1999, in the framework of the Cooperation Agreement, 11 contracts have been successfully fulfilled.
