TecViewTM3D is at the heart of Scan3D immersion scanner solution. With its added capabilities in term of complex 3D motion control, interactive inspection plan- ning and variety of analysis tools, the Scan3D has un matched scanning features. Complex ultrasonic inspec- tions can be performed quickly and easily. For part im- port, normalized 3D step file format is used. Once CAD geometry is imported, Scan3D associates the part surfaces to the appropriate scanner axes and creates a parametric space that defines the surface. TecView3D also provides Sound Path Calculation capabilities. This module is very useful when combined with teach and learn process. It can calcu- late the entry and exit points of the ultrasonic waves and ensure an optimal sound transmission and reception. TecView3D also allows live data analysis creating C-Scans as soon as the first A-Scans appears on the screen. We could define up to 16 gates to op- timize data analysis by performing amplitude, time-of-flight and thickness based C-Scan imaging simultaneously. Plus, material interface gate type can be used to identify and define different material layers, allowing for depth or thick- ness measurements to be done on each existing material layer.
