Tools Overview
Visual Work Instruction (VWI)
A Visual Work Instruction (VWI) is a CAD Model based representation of technical instructions and product manufacturing information. Outsourced VWIs are intended for use as walkthroughs of the relevant details for the scope of work. This is accomplished through presentation of a product’s build/assembly sequence and design intent.
VWIs are created using the SAP Visual Enterprise.RH file format and are used across both Carrier (CVN) and Submarine (VCS/VPM) programs at Newport News Shipbuilding.

Siemens PSD+JT
PDF+JT is a 3D file format similar in form and function to an ISO standard 3D PDF. PDF+JTs are created by our program partner, Electric Boat, and used to convey technical product information in both a PDF and CAD model based format. These documents are assembled with relevant product manufacturing information (PMI) similar to paper based drawings with the additional benefit of embedded lightweight .JT model files for use as a visual aid.
PDF+JTs are created through use of Siemens software and are used for the Columbia (CLB) and Virginia Payload Module (VPM) programs at both Electric Boat and Newport News Shipbuilding.
