1. A computer-implemented method, comprising: identifying an analytical representation of a plurality of physical elements in a computer aided design (CAD) model, the analytical representation comprising a plurality of wire frame elements associated with connectivity conditions, one or more of the plurality of analytical elements corresponding to one or more of the plurality physical elements; establishing an association between corresponding analytical and physical elements such that a modification to one element causes a modification to a corresponding other; and detecting an error when a distance between a wireframe element and a corresponding physical element is greater than a tolerance distance.
