3-D Modeling and Geometric Conversion
SURVICE Metrology uses the latest data processing, modeling, and CAD software packages to develop detailed solid, surface, and/or hybrid 3-D models in a variety of geometric file formats. We also have extensive experience modifying and enhancing existing models as well as converting models to other geometric formats.
Experience Matters
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.
