A method for maintaining a selected configuration for a structure, the method comprising: receiving metrology data for a support system, while the support system holds the structure; and determining whether a current configuration of the structure is within selected tolerances of the selected configuration based on the metrology data; and reconfiguring the support system to move the structure into the selected configuration in response to a determination that the current configuration is not within the selected tolerances of the selected configuration, wherein determining whether the current configuration of the structure is within the selected tolerances of the selected configuration for the structure based on the metrology data comprises: identifying a plurality of local coordinate systems for a plurality of supports of the support system using the metrology data; identifying a structure coordinate system for the structure using at least one of the metrology data or at least two of the plurality of local coordinate systems; and determining whether the current configuration of the structure is within the selected tolerances of the selected configuration for the structure based on whether an X-Y plane of the structure coordinate system is substantially parallel to a reference X-Y plane of a global coordinate system, wherein reconfiguring the support system comprises: reconfiguring a selected portion of the plurality of supports of the support system to align the structure coordinate system with the global coordinate system such that the X-Y plane of the structure coordinate system is substantially parallel to the reference X-Y plane of the global coordinate system. receiving metrology data for a support system, while the support system holds the structure; and determining whether a current configuration of the structure is within selected tolerances of the selected configuration based on the metrology data; and reconfiguring the support system to move the structure into the selected configuration in response to a determination that the current configuration is not within the selected tolerances of the selected configuration, wherein determining whether the current configuration of the structure is within the selected tolerances of the selected configuration for the structure based on the metrology data comprises: identifying a plurality of local coordinate systems for a plurality of supports of the support system using the metrology data; identifying a structure coordinate system for the structure using at least one of the metrology data or at least two of the plurality of local coordinate systems; and determining whether the current configuration of the structure is within the selected tolerances of the selected configuration for the structure based on whether an X-Y plane of the structure coordinate system is substantially parallel to a reference X-Y plane of a global coordinate system, wherein reconfiguring the support system comprises: reconfiguring a selected portion of the plurality of supports of the support system to align the structure coordinate system with the global coordinate system such that the X-Y plane of the structure coordinate system is substantially parallel to the reference X-Y plane of the global coordinate system. identifying a plurality of local coordinate systems for a plurality of supports of the support system using the metrology data; identifying a structure coordinate system for the structure using at least one of the metrology data or at least two of the plurality of local coordinate systems; and determining whether the current configuration of the structure is within the selected tolerances of the selected configuration for the structure based on whether an X-Y plane of the structure coordinate system is substantially parallel to a reference X-Y plane of a global coordinate system, wherein reconfiguring the support system comprises: reconfiguring a selected portion of the plurality of supports of the support system to align the structure coordinate system with the global coordinate system such that the X-Y plane of the structure coordinate system is substantially parallel to the reference X-Y plane of the global coordinate system.
