There was that problem with CAD software on the A380: German teams used CATIA version 4, while French had upgraded to version 5, resulting in incompatibilities.
"By late autumn, a team of around 200 German mechanics was in Toulouse along with several hundred kilometers of electrical cables to be installed in the first planes. But after weeks of painstakingly threading thousands of veins of copper and aluminum wire around the walls and floor panels of the airframes, the teams had run into a maddening snag: the cables were too short.
"The wiring wasn't following the expected routing through the fuselage, so when we got to the end they weren't long enough to meet up with the connectors on the next section," said one German mechanic, who said he arrived in Toulouse in early 2005. He asked not to be identified out of fear that he might lose his job. "The calculations were wrong," he said. "Everything had to be ripped out and replaced from scratch." --- nytimes https://archive.vn/uLIqa#selection-603.204-617.419
