Arc Second, Inc., recently announced that its PocketCAD Software Development Kit (SDK) is based on the Windows CE.NET embedded operating system, the newest version of the Microsoft Windows CE embedded operating system. The re-architecting of PocketCAD for the Windows CE.NET operating system allows for a new range of opportunities for PocketCAD developers. Commercial developers will now be able to embed Arc Second's mobile CAD technology into their own mobile applications. The new SDK allows developers to work in a variety of languages including Visual Basic and C#. Several new capabilities have also been added to the already-powerful PocketCAD SDK.
