Patent ID: 8548619

Claim:
A maintenance system for an assembly, comprising: a metrology device for measuring a location of at least one characteristic of an as-built assembly relative to a parametric reference point of the as-built assembly and creating as-built parametric data regarding the location, the as-built parametric data comprising a relationship constraining the measured location of the characteristic relative to the parametric reference point; a storage medium containing an as-built computer-aided design model of the assembly reflecting the as-built parametric data of the as-built assembly obtained from the metrology device and representing the location of the characteristic relative to the parametric reference point, the as-built computer-aided design model containing data associated with a theoretical computer-aided design model of the assembly and imported into the as-built computer-aided design model, the as-built computer-aided design model being created in synchronized real-time reflecting the as-built parametric data of the as-built assembly; and a displaying means for displaying the as-built computer-aided design model.
