LEDAS Supports CAD Research at Purdue University
 NOVOSIBIRSK,
Russia, Aug 10, 2009 - LEDAS Ltd., an independent provider of computational
components and software development services for the CAD/PLM (Computer-Aided
Design and Product Lifecycle Management) market, today announced that
ongoing research at Purdue University
(USA) in the field of CAD user interfaces, partially supported by LEDAS, has
recently resulted in creation of a prototype CAD system that allows users to
draw as natural as possible just as one would draw on paper. In 2007 LEDAS
granted a free academic license for its geometric constraint solver LGS 2D
to Purdue University. Since then a research group under supervision of Prof.
Karthik Ramani has successfully integrated LGS 2D with their prototype with
presenting the results at two scientific events. The first presentation was
done at the Sixth Eurographics Workshop on Sketch-Based Interfaces and
Modeling, Aug 1-2, New Orleans, USA, co-located with SIGGRAPH 2009. Another
paper will appear in the proceedings of the
ASME 2009 International Design
Engineering Technical Conferences & Computers and Information in Engineering
Conference IDETC/CIE 2009, August 30 - September 2, 2009, San Diego, CA,
USA.
“Beautification of freehand sketches is integral for building robust
sketch understanding systems and sketch-based interfaces for CAD,” said
Sundar Murugappan, a Ph.D. student and co-author in both the publications.
Professor Ramani added that “Many of the current methods for beautification
do not consider some important information implied in the sketches such as
spatial relationships (geometric constraints) between primitives. We present
our ongoing work, a suggestive interface for constraint-driven
beautification of freehand sketches which provides multiple interpretations
of the freehand input, from which the user can choose the intended result.”
The research was supported by the U.S. National Science Foundation (NSF)
Computer and Information Science in Engineering (CISE) – Information and
Intelligent Systems (IIS).
“Purdue University is famous for its world leading researchers in the
field of computer-aided design and geometric constraint solving, and we are
very proud to support their research aimed at building user interfaces for
tomorrow’s CAD systems,” said David Levin, CEO and founder, LEDAS Ltd. “We
are also supporting several universities in Russia and China by granting
them free academic licenses for our computational software. A combination of
our industrial experience in the field of constraint-based design with
state-of-the art research results in invention of the new generation CAD
systems.”
In the framework of its academic licensing program LEDAS grants free
licenses for 2D and 3D versions of its geometric constraint solvers LGS to
non-commercial Academic and Educational organizations. A Free Academic
Licensing approach gives researchers and students a unique opportunity to
access this state-of-the art parameterization technology.
About LGS 2D
The LGS 2D geometric constraint solver is a computational module,
engineered to support two-dimensional history-free parametric design in CAD
and computer graphics systems, as well as many other applications that
require geometric and dimensional relationships to be set between
geometrical objects. LGS 2D supports creation and modification of geometric
models by means of (explicit or implicit) constraints, which are solved
simultaneously.
