Comments on: U.K. probes costly tech failure for submarines

Computer-aided design failures contribute to delay of three nuclear subs, $1.57 billion shortage.

Was it really the CAD system

The name of the CAD system was not mentioned; understandably. But was it really the CAD system? Management of CAD data has always been an issue that separates the average CAD user from the super users.
Was it the integrity of the 3D models? Different from the 2D drawings? Often 3D model standards are not developed or enforced and rarely do companies have a "check cycle" for the 3D models while having long wasteful cycles for 2D drawings.
What was the real issue? Were there tolerance issues perhaps that have nothing to do with the CAD system unless the discussion carries into 3D annotation and the master model concept.
Certainly some CAD systems are better then others but it is hard to accept that the CAD system was at fault without some detail of the root causes for whatever problems were happening on this project.

Coincidence??

The CAD system in question is also the one being used on the FCS program in the US which is also the subject of reviews on the inability of the system and its work in progress data manager to fulfill the promises at onset of the program. The Integrated Collaborative Environment (ICE) for the FCS program is at risk and is also subject to review on its inability to provide substantive value. This is the same CAD system that is at question at BAE in the UK. Coincidence?? Not at programs of this scale and with this much at risk.
