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.
Visit our How to Download section for the direct link to the software needed to render VWIs through SAP’s free Visual Enterprise Viewer (VEV) program.
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.
Visit our How to Download section for the direct link to the software needed to render PDF+JT files through Siemens free JT2Go program.
NOTE: Model Based Disclosures (VWI and PDF+JT) are released with intended contractual dimensions. The vendor may use the native measurement tools from the relevant CAD rendering program to obtain additional measurements, however, measurements obtained in this manner are for Information Purposes Only.
Visual Work Instruction (VWI)
SAP provides a useful reference on its measurement tool for Visual Enterprise Viewer (VEV) which covers measurements, delta measurements, repositioning, cross sections and modification of global measurement settings. This reference can be found within SAP’s documentation here.
PDF + JT
Siemens provides a useful reference on its measurement tool for JT2Go version 12.3 on its documentation site. Topics covered include measurement of single parts, distances and angles, approximations, and preferences. This reference can be accessed here.

Newport News Shipbuilding (NNS) is committed to providing a safe environment for all persons visiting or working at NNS. This means that contractors working at NNS and NNS worksites are required to meet minimum safety standards before contracts can be awarded. They are also required to maintain these standards for the duration of their work at Newport News. Also, while contractors are expected to have effective safety programs and to monitor and comply with applicable laws and regulations, there are some situations where procedures specific to NNS apply. The Newport News Contractor Environmental, Health and Safety Resource Manual was developed to assist potential and existing contractors in these areas. The manual describes the contractor health and safety evaluation process, describes specific EH&S programs that are considered critical and lists additional health and safety resources that may be useful to contractors. Many of the topics are contractual requirements. This manual is not inclusive of every possible Environmental, Health and Safety topic and it is the responsibility of the contractor to be knowledgeable of and comply with additional laws and regulations.
