DriveWorks Live Integration Theme is a theme used by DriveWorks Live that hosts the DriveWorks Live Web API. It allows DriveWorks to integrate directly into a new or existing website, giving you the ability to customize the website itself to your liking, instead of having to use the pre-made DriveWorks forms through an iFrame.
In DriveWorks, users can group multiple projects into one top-level project. Certain projects lend themselves to grouping small child projects into one large project. For example, if I wanted a project for a layout of conveyor belts, I could have one project for one conveyor section, and then the layout project could contain multiple conveyor section projects and verify they all had the same width so that they would be compatible.
