description This paper presents the results of a comprehensive analysis, from the geometric point of view, of the LHC dipoles up to now manufactured. The progressive downgrading of the magnet imposed shape has been monitored from the first magnet assembly stage to after the cold test. The efficiency of the corrective re-shaping action is critically undermined by the analysis results. Data concerning the error on sagitta, end positions and sextupolar corrector positions are provided for the magnets produced up to July 2003. Implications of aligning out-of-tolerance dipoles by the ends are also discussed.
