Airbus has selected
CoreTechnologie as the preferred vendor to validate the 3D STEP AP242 data for
LOTAR (Long Term Archival and Retrieval).
Airbus chose this approach for its new A350 XWB (Xtra Wide-Body) aircraft that will be introduced in 2014.
Airbus and CoreTechnologie participate in the LOTAR consortium. The objective is to develop standards for long-term archiving and retrieval of digital data, such as 3D CAD and PDM information which allows data to be read and used again throughout its life cycle, regardless of environmental changes in computer applications used. LOTAR recommendations stipulate that archived files must first be validated to ensure the accuracy of the data for future use. Gauthier Wahu, CoreTechnologies Chief Technical Officer stated We are excited to implement these standards for such an impressive company like Airbus. This joint venture was instrumental in the last release of CoreTechnologies flagship software product; 3D_Evolution, which now includes a fast and reliable validation function for STEP AP242.
Concretely, validation is based on data and properties included in the STEP file provided by the native system, in this case CATIA. These validation properties of the model primarily relate to PMI, assembly, visualization data, volume, surface and center of gravity. After importing the STEP file, 3D_Evolutions validation tool, computes its properties and also compares them with values provided in the original file. Reporting functions allow measured deviations to indicate variances in the file, thus allowing the user to correct the file prior to archiving.?
