Driving Dimensions for Google SketchUp Public Beta Downloads Top 3,000 in Three Months

Novosibirsk, Russia, February 2, 2009 — LEDAS Ltd, a leading provider of computational software components for computer-aided design (CAD) systems, today released the fourth preliminary version of its Driving Dimensions plugin for Google SketchUp and announced that more than 3,000 copies were downloaded in the first three months since the free public beta was made available in end of October 2008. The plugin is available as a free download at

Driving Dimensions plugin offers easy-to-use parameterization tools, which considerably reduce the time required to make parametric changes to the existing 3D models and open new modeling capabilities for SketchUp users. Version 0.4 introduces new types of driving dimensions — distance between a vertex and a face. Advanced treatment of circular arcs (now they are not rigid and can be changed automatically to satisfy driving dimensions) and improved Undo functionality are two other important features of the new version. The new and advanced functionalities of Driving Dimensions 0.4 are demonstrated in several sample models available at

«While Driving Dimensions plugin really opens up new possibilities of parametric design in SketchUp, many users still do not see its added value with respect to the built-in tools — Scale, Tape Measure, Dynamic Components,» said Dmitry Ushakov, Director of Product Management, LEDAS Ltd. «To overcome this misunderstanding, we have answered typical questions about Driving Dimensions and put the relevant FAQ at our web site.» More information can be found at

Driving Dimensions is compatible with Google SketchUp 6 and 7 (both Free and Pro versions) running on Windows 2000/XP/Vista with no specific hardware requirements. For more details about the new release of Driving Dimensions for SketchUp, sample models, video tutorials and online help please visit

About Driving Dimensions

Driving Dimensions are end-user applications developed by LEDAS as plugins for popular 2D and 3D modeling systems to provide advanced parameterization capabilities to their users. Driving Dimensions are based on the Variational Direct Modeling technology, which uses direct (history-free) editing model elements, preserving its design intent, expressed by explicit and implicit driving dimensions (linear, angular, radial) and geometric constraints. Simultaneous satisfaction of geometric and dimensional constraints is achieved with LGS variational geometric solver, which is being developed by LEDAS since 2001 and is available for licensing to all CAD developers.


LEDAS Ltd. is an independent software development company founded in 1999; it is based in Novosibirsk Scientific Centre (Akademgorodok), Siberian Branch of the Russian Academy of Science. A leader in constraint-based technologies, LEDAS is a well-known provider of computational software components for PLM (Product Lifecycle Management) solutions: geometric constraint solvers for CAD/CAM/CAE, optimization engines for Project Management, Work Scheduling and Meeting Planning as well as interval technologies for Knowledge-Based Engineering and Collaborative Design. The company also provides services for PLM market: software development, consulting, reselling as well as education and training. More information about LEDAS is available at
