The present invention is a method for accessing a model, wherein the model incorporates a plurality of roof truss assemblies, wherein the assemblies are comprised of a plurality of members; detecting at least one interface between at least two roof truss assemblies, and wherein the interface type is detected; recording, by at least one processors, a interface type, wherein a set of required values based on the interface type are identified; calculating a set of actual values associated with the interface; comparing if the set of actual values is within the required values; identifying a modification to at least one roof truss assembly involved in the interface; incorporating the modification into the model; and analyzing the model for newly created interfaces between a set of members of the model.
