Scanning and Modeling of the Assault Amphibian Vehicle (AAV)

Assault Amphibian Vehicle Command Model 7A1 (AAVC7A1) Project Summary

Design Mill, Inc. (DMI) supported the 3D laser scanning and modeling of the AAVC7 A1 for use in integration and testing. Using our advanced portable scanners, we were able to scan the AAVC7 A1 on location in Charleston, South Carolina.

Multiple 3D scans of the vehicle and required components were made of the interior and exterior. As the laser scanner is passed over the object, it captures data about the shape, measurements and texture of the object and outputs point cloud data sets. During scanning operations, our scan technicians ensured the highest quality videos and photographs were taken. We have a systematic approach to catalogue all scanned data along with the pictures and videos captured into a complete system library that will be utilized during the 3D modeling process.

Our 3D modeling technicians exported the scanned data sets to CAD software, using the photographs and videos as reference we were able to quickly reproduce complete and accurate 3D models of the vehicle and its components.

Uses for the scan data, models and animations include:

• Reverse Engineering – Design and locate brackets, mounts and components utilized in the interior.

• Finite Element Analysis – Shock and vibration testing on interior mounts.

• Human Factors Engineering – Determine the placement of components such as seats, communications equipment and workstation elements to ensure Marines could use the equipment safely and effectively.

• Technical Drawing – Drawing views from our Pro/Engineer models were used to create technical drawing packages.

• Interactive 3D PDF – PDF fi le that lets you interact with the model.

• Interactive Electronic Technical Manual (IETM) development

The models and animations we created were incorporated into VENOM™(Virtually Enhanced Next-Generation Optimized Model). VENOM™ is an IETM developed by DMI and is currently being delivered to SPAWAR as a standalone product. VENOM™ allows the user to select a 3D vehicle and then drill down to the component level to access the support documentation for the associated item. VENOM™ features include:

• 360 degree digital animation of the vehicles

• Fly through Animations

• Interactive 3D Models

• Interactive Cabling Diagrams

• 3D Views of Cable Layouts

• User manuals / technical documentation / training guides provided

Additional support is being provided to the Assault Amphibian Schools Battalion in Camp Pendleton, California through scanning and modeling of the AAVP7A1 for use in training applications.

The hull configuration for the AAV Family of Vehicles (FOV) is the same, so we were able to reuse the exterior scan data sets and models from the C7A1 for the P7A1. The interior of the P7A1 was scanned on location in Camp Pendleton, California. Using the P7A1, parts and components provided by the AAV school house, DMI scanned and modeled the majority of removable components.

The resulting models and animations we created were used as training aids in the formal school house. Using provided lesson plans and specific requests from the school house, DMI has also created an Interactive Multimedia Instruction (IMI) for the AAVP7A1.

The IMI features include:

• Realistic 3D rendered models that show actual detail and functionality

• Instructional Animations

• Vehicle Animations

• Interactive Procedural Frames

• Interactive Practical Applications

• Audio Text Narration

• Comprehension Checks

• Web accessible, making it available to the entire AAV user community

The IMI was developed to customer specifications following industry standards and Department of Defense (DoD) and United States Marine Corps (USMC) requirements to include, but not limited to:

• Military Handbook 61A Confi guration Management Guidance

• TECOM College of Continuing Education (CCE) Design and Development Standards (DDSv.2)

• MarineNet Courseware Development Technical Standards

• SCORM compliant
