SURVICE Metrology is highly skilled in developing geometric models of complete domestic and foreign aircraft, rotorcraft, ground systems, watercraft, missiles, structures, or individual components/systems. We are experienced in using numerous modeling formats, including FASTGEN, BRL-CAD, ACAD, SolidWorks, AutoCAD, and Creo/ ProEngineer. In addition to the aforementioned Government and commercial CAD software, SURVICE utilizes geometric processing tools such as PolyWorks, GeoMagic, MAGICS, RapidForm, HyperMesh, Cubit, and Rhino 3-D to manipulate and convert point cloud datasets and polygon meshes to the required deliverables.
Mechanical Design and Geometric Conversion
Geometric models can be developed “from scratch” using a variety of data sources, including manufacturer’s line drawings, intelligence data, photographs, or other types of design data. In addition, SURVICE has a wealth of experience converting manufacturers’ CAD files into applicable formats for development of target descriptions, FEA and CFD meshes. We have also developed a number of tools for conversion, visualization, and utilization of geometric data, to include high-performance raytracing tools. Many of these tools are used by industry and government users. And when design data are not available, SURVICE can leverage its state-of-the-art 3-D coordinate measurement and laser scanning equipment and processes to collect and postprocess data from physical assets efficiently.
Reverse Engineering Expertise
Whether digitizing a large vehicle/asset or a small part for reverse engineering, the most efficient process to capture the level of detail and accuracy will be determined and applied. SURVICE commonly utilizes two main reverse-engineering methods, determined by the project’s specific design and/or integration needs. The first process (“Scan to CAD”) involves the collection of point cloud data using a 3-D scanner and subsequent post-processing or on-site asset exploitation to develop 3-D geometries and/or technical data packages. The second process (“Direct to CAD”) involves the collection of discrete point measurements using a Faro Arm and utilization of these measurements to directly produce feature-based, parametric, 3-D CAD models in commercial CAD packages such as SolidWorks and Pro/Engineer. Both processes are supplemented with hand measurements of geometric and dimensional data where most effective and efficient.
