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.?
