The present disclosure is directed to a system and method for generating a three-dimensional (3D) assembly on-demand in a product management system, such as a product lifecycle management (PLM) system. The method includes electronically creating and storing one or more instance objects in the product management system. Another step includes electronically mapping the one or more instance objects to function information in the product management system. The method also includes electronically receiving, via a network portal, user input regarding a selection of one or more functions representing product information from the product management system. Still another step includes electronically generating the 3D assembly based on one or more of the mapped instance objects and the user input.
