China's NWPA to Use LEDAS Geometric Solvers
 NOVOSIBIRSK,
Russia, Feb 28, 2008 - LEDAS Ltd., an independent software provider of
computational components for PLM and ERP, announces of licensing policy of
its 2D and 3D geometric solvers to College of Astronautics of Northwestern
Polytechnical University (NWPU), China. Academic Licensing approach gives
unique opportunity for researches and students to access parameterization
technology.
“We have heard that your company had launched an academic licensing
program for LGS2D/3D. It is attractive and we want to join this program As a
part of ongoing research, we need to develop a CAD application based on
solid modeling engine and incorporating a geometric constraint solver. We
recently came across of LEDAS products, the LGS 2D/3D solver” says Jingshi,
Liu, a teacher of College of Astronautics.
Аbout the LGS family solvers
LGS 2D/3D is a cross-platform software. It is set of libraries that runs
under all Windows, Linux, *BSD, AIX and other OS. Being written itself in
C++, LGS has a C-based API that allows one to integrate it into a broad
range of software applications (even written not in C/C++).
A sample test application for LGS called Lege’n’d is also available as
part of the Evaluation version of LGS 2D/3D. They were created with the Open
CASCADE open-source framework. The Lege’n’d 2D and 3D applications can be
used to test the entire functionality of the LGS 3D without the need to
integrate the solver into other software packages. A set of representative
examples for Legend's 2D/3D is also supplied.
LEDAS Geometric Solvers 2D/3D support creation and modification of the
geometric models by means of (explicit or implicit) constraints. Typical
geometric objects are points, lines, circles, planes, cylinders, spheres,
arbitrary curves, surfaces and swept surfaces. Objects can be fixed in an
absolute coordinate system or relative to each other (the latter feature is
provided by the so-called rigid sets of objects). Set of geometric
constraints includes logical constraints between geometric entities (like
coincidence, parallelism, tangency, etc.) and dimensional constraints (that
specify the required values for given distances, angles or radii). LGS moves
and rotates objects to the positions where all constraints are satisfied by
performing minimal transformations of initial configuration. It also renders
standard CAD functions - ‘move under constraints’ and diagnostics of over-
and under-defined parts of a model.
LGS 2D/3D are based on the LEDAS’ state-of-the-art engine provide
affordable solution for those who need a strong variation and
constraint-based functionality in CAD, modeling, or engineering software.
Through the scalable architecture of LGS, variation and parametric
techniques become available in a wide range of the products including
desktop CAD/CAM/CAE, and object modeling tools, assembly design and analysis
and others.
About NWPU
Northwestern Polytechnical University is China’s only research-oriented,
multi-disciplinary, and international university of science and technology,
which simultaneously excels at Aeronautics, Astronautics, and Marine
Engineering. The School of Astronautics is a very important part of the
“Aeronautics, Astronautics and Marine Engineering” characteristic of the
Northwestern Polytechnical University. It was originally founded in 1958 as
Department of Astronautic Engineering, which is one of the earliest and
premier schools in astronautics among Chinese universities. In order to
adapt to the development of astronautic science and technology, the School
of Astronautic Engineering was founded in December 1988, based on the former
Department of Astronautic Engineering. In July 2003, the School of
Astronautic Engineering was renamed to School of Astronautics. For more
