Abstract: A system for concurrent CAx workflow includes a collaborative server that manages a model of an engineering object, the model comprising at least design data and analysis data corresponding to the design data, a design client for editing of the design data by a design user, an analysis client for editing of the analysis data by an analysis user concurrent with editing of the design data by the design user; and wherein the collaborative server and the analysis client are collectively configured (i.e., one or both are configured) to enable the analysis user to edit the analysis data, view a plurality of geometric elements within the design data, and create a reference within the analysis data to a selected geometric element of the plurality of geometric elements within the design data. A corresponding apparatus, method, and computer-readable medium are also disclosed herein.

Abstract: A system for scalable multi-user CAD may include a traffic consolidation server consolidating feature edits from CAD workstations editing one or more proximate regions of an engineering object. The traffic consolidation servers may transmit feature changes to other workstations editing the proximate regions of the engineering object while forwarding the feature changes to a CAD model server. CAD model servers may be configured to receive consolidated feature changes pertaining to an assigned region of the engineering object. An assignment server may balance processing loads on traffic consolidation servers. Methods and apparatus corresponding to the above system are also disclosed herein.
