LEDAS Releases Driving Dimensions v.1.3 for Google SketchUp

More than 20,000 SketchUp users downloaded LEDAS Driving Dimensions toolset for easy parametric modification of their 3D models

Novosibirsk, Russia, May 14, 2010 - LEDAS Ltd., the independent provider of variational design tools, technology components, and software development services for the CAD/CAM/CAE/PDM market, today announced the availability of version 1.3 of its Driving Dimensions plug-in for Google SketchUp software, a simple in use toolset for parametric modification of history-free 3D models.

Version 1.3 supports new platforms and contains several improvements and fixes. Answering numerous requests by the users of Windows 7 and Mac OS X v.10.6 operating systems, LEDAS development team focused on supporting these new platforms for its SketchUp plug-in. The functionality of multi-document interface (MDI) on Mac platform has been improved. Version 1.3 also includes several fixes of internal errors reported by Driving Dimensions users.

About Driving Dimensions and LGS 3D

Driving Dimensions plug-in v.1.3 is compatible with Google SketchUp v.6 and 7.1, and has been thoroughly tested on the 32-bit versions Windows XP, Vista, and 7, as well as on Mac OS X 10.6.

Driving Dimensions for SketchUp is a plug-in that performs parametric modifications of 3D geometric models in very simple and intuitive way. With Driving Dimensions, users can modify any dimension (length, distance, radius, or angle) in any SketchUp model with just one click. All driving dimensions set in one model are satisfied simultaneously. The simplicity of the user interface of Driving Dimensions plug-in hides a very strong set of mathematical algorithms in the field of geometric constraint solving. Parametric design has never been so easy – even for beginners.

Driving Dimensions v1.3 is based on the latest version of LGS 3D, a geometric constraint solver integrated into a dozen commercial CAD packages. The latest release, version 3.0 of LGS 3D, contains many improvements in stability and performance, which are also available to SketchUp users.

LGS 3D geometric constraint solver, technology that LEDAS has developed since 2001, is available for licensing to all CAD developers. More information about LGS 3D can be found at, while Driving Dimensions portfolio of end-user applications is presented in details at
