LEDAS Ports its Driving Dimensions plugin for Google SketchUp to Mac and Reports 10,000 Downloads of Windows Version

Novosibirsk, Russia, June 23, 2009LEDAS Ltd., an independent provider of variational design tools known as Driving Dimensions plugins for different CAD platforms, today announced version 1.1 of its Driving Dimensions plugin for Google SketchUp, a free 3D modeling software. With this plugin SketchUp users can parametrically edit their models in a very simple and intuitive way.

Version 1.1 introduces the ability to apply driving dimensions between geometric objects included into one group. Enhancements of the graphical user interface include a new toolbar button that simplifies the access to online help and improved usability when selecting two dimension arguments with a mouse.

With release 1.1 LEDAS also made a significant step toward Mac community of SketchUp users: now Driving Dimensions for SketchUp runs not only on Windows 2000/XP/Vista, but also on Mac OS X platform. It became possible after porting LGS, a variational geometric solver developed by LEDAS, to Mac OS X.

"In our work we were seriously inspired by the constantly growing user base of our Driving Dimensions plugin for SketchUp,” said Dmitry Ushakov, Director of Product Management, LEDAS Ltd. “In less than eight months after we released a first public beta, about 10,000 SketchUp users from 125 countries downloaded it from our website. With its growing popularity Mac OS X platform attracts more and more attention of CAD developers. We are excited to offer advanced parametrization tools integrated with a popular free 3D modeling software for Mac users."

A free version of Driving Dimensions 1.1 for SketchUp 6 and 7 running on Windows 2000/XP/Vista and Mac OS X can be downloaded at The free version is not intended for commercial use and is limited in the maximum driving dimensions entities that can be added to one SketchUp model. The Pro version is available from share-it! online store for only $45 per single user license.

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 (SketchUp and Rhinoceros are two examples). 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.
