SCALABLE MULTI-USER CAD SYSTEM AND APPARATUS

摘要

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.

1. A system for scalable multi-user CAD, the system comprising:
a plurality of CAD workstations, each CAD workstation thereof configured to store a local CAD model, render the local CAD model on a display, receive editing sequences from a user, generate feature changes to the local CAD model from the editing sequences, and transmit the feature changes to a traffic consolidation server assigned to the CAD workstation; a plurality of traffic consolidation servers, each traffic consolidation server thereof configured to receive and consolidate feature changes from at least one CAD workstation to provide consolidated feature changes and transmit the consolidated feature changes to a CAD model server; a CAD model server configured to receive the consolidated feature changes and generate a plurality of storage change transactions corresponding to the feature changes and provide the storage change transactions to a storage server; and a storage server configured to store data corresponding to a global CAD model, receive the storage change transactions, and change the data corresponding to the global CAD model.
