GCS Earns SolidWorks Certified Gold Product Status
Newest Version of Conisio Software Enhanced for Deploying PLM across the Enterprise

LAS VEGAS, NV - January 20, 2006 - Conisio® software from GCS Scandinavia recently earned the status of Certified Gold Product from the SolidWorks Solution Partner Program, representing the highest level of integration with SolidWorks® software. Conisio is the first and only commercial engineering document management system entirely integrated within Windows Explorer. The system supports any application running on a Windows-based computer including CAD programs such as SolidWorks and all Microsoft Office® programs such as Word, Excel, PowerPoint, Project, and Outlook. Rather than struggle with cumbersome interfaces, users perform all functions in Conisio through Windows Explorer or one of its other integrations.

"Our entire team is impressed with the functionality and integration of Conisio," says Brian Houle, manager of the SolidWorks Solution Partner Program. "Its integration with SolidWorks and operation within Windows Explorer maximize the productivity of SolidWorks users, and we are pleased to award the software our Certified Gold Product status."

"We are honored that Conisio's value for SolidWorks users has been recognized," explains GCS President Kenneth Hallberg. "We have a close working relationship with SolidWorks and look forward to supporting its broad user community in leveraging our unique approach for powerful, simple, and affordable engineering document management."

GCS recently launched Version 6.3 of Conisio with significant enhancements for readily deploying product data management (PDM) and related product lifecycle management (PLM) initiatives across the enterprise. A unique file vault replication technology enables multiple users at different locations (even those widely dispersed around the world) to quickly access engineering documents and information stored on the system. This replication function is now verified to readily handle low bandwidth and high latency, thus enabling systems with limited connection speeds to conveniently access the central database. Conisio 6.3 also now supports SQL Server 2005, Microsoft's next-generation integrated data management and analysis solution helping organizations deploy enterprise applications and share data across multiple systems.

A completely new feature in Conisio 6.3 is Cold Store functionality that enables the system to schedule file vault compression using Zip- technology. Versions of documents can be stored off-line and intermediate working versions can be permanently deleted. This feature is easy to set up and schedule via Conisio's Administration Tool, thus reducing extended storage requirements while maintaining a complete audit trail of document changes.

The user interface of Conisio 6.3 includes document thumbnail previews that display simplified sketches of parts in an assembly or product, together with a hierarchal listing of part documents associated with those components. User-defined reference hierarchies for documents are easily set up and modified using "drag and drop" and other features conveniently for relating particular files.

"Conisio 6.3 reflects our overall strategy of delivering high-performance technology with an easy-to-use, simple interface for users both within and outside the technical workgroup," says Hallberg. "This enables companies to put PLM functionality on the desktops of a wide range of users than is otherwise possible."

Hallberg explains that because users perform all functions through Windows Explorer or one of its other integrations such as SolidWorks, for example, the familiar look and feel results in early user acceptance, minimal training, quick implementation and early return on investment.

"Conisio is one of the easiest and most affordable ways to implement PDM and related product lifecycle PLM initiatives," he notes. "In significant contract awards every week, Conisio is selected over established players in the mid-range PLM market on the basis of its easy-to-use interface, minimal resources needed for implementation, tight integration with multiple CAD systems, and a demonstratable industry-leading ROI."

Conisio will be demonstrated in GCS booth 117 at the SolidWorks World 2006 user conference and exposition.
