Success stories: customers, partners, and friends (1999 – 2017)


Open Design Alliance (ODA), customer for software development


The Open Design Alliance is a non-profit consortium of over 2,000 software developers and users committed to promoting open, industry-standard formats for the exchange of CAD data and CAD legacy data. The ODA technology platform provides users with the tools to create a wide range of applications, including custom data access and editing utilities, visualization tools, and even full-scale CAD systems. The platform also supports the use of both DWG and DGN files, with import and export capabilities to other file formats. The Open Design Alliance maintains the OpenDWG® library and publishes the OpenDWG file specification.

Cooperation between ODA and LEDAS started in the ancient Dutch city of Leyden where in April 26-29, 2009 was held a conference of Open Design Alliance. This was in all details described by Dmitry Ushakov in his article “The prodigal son of Autodesk“. The result of this contact was announced a year after that conference in the following press-release “ODA and LEDAS Implement Parametric Drawing Tools Compatible with the DWG 2010 file format”.

The Open Design Alliance (ODA) and LEDAS announce the integration of version 3.0 of the LEDAS LGS 2D geometric constraint solver through the ongoing cooperation between the two organizations. Version 3.0 of the LGS 2D geometric constraint solver is an upgrade of the initial integration with the ODA platform implemented in 2009 when the cooperation between the ODA and LEDAS began. Since last year, the constraint solver has been a component available to ODA members who require constraint support for their applications. Implementation of the constraint system, jointly developed by ODA and LEDAS, is fully compatible with the DWG 2010 file format.

Dmitry Ushakov, LEDAS Director of Product Management, will present the new version and its integration with the ODA platform at the ODA World Conference, Orlando, FL USA, May 4–5. The updated solution contains new support for NURBS curves, equal curvature geometric constraints, memory management tools, and many other improvements. Mr. Ushakov will also present a demo application that everyone can use to evaluate parametric drawing technology and its compatibility with the DWG file format. Attendees of the ODA Technology Exchange will learn how they can embed parametric drawing technology into applications for different platforms.

Arnold van der Weide, President of the ODA, stated, “The third-party component solution delivered by LEDAS has been a success for both the ODA and LEDAS — an active cooperation between development teams has ensured an efficient integration and robust solution.” Mr. van der Weide added, “I’m looking forward to seeing the results of the cooperation directly from Dmitry Ushakov during his presentation at the ODA Technology Exchange portion of the ODA World Conference in May.”

“LEDAS is the only vendor-independent provider of geometric constraint solvers for parametric drawing and design applications,” said David Levin, LEDAS CEO and founder. “Our constraint solvers were proven to be robust by embedding into many CAD systems, and we are happy to see LGS 2D integrated with the ODA platform, a leading industrial system for technical graphics applications. We offer ODA members the opportunity to license our ready-to-use solution at a very affordable price.”

ODA members who have a license for the LEDAS LGS 2D geometric constraint solver can integrate the new 3.0 version easily to provide the enhanced support for parametric and constraint drawing to their applications.
