According to Bob Haubrock, Senior Vice President of Product Engineering Software (NX), Convergent Modelling marks the biggest change in computer-aided design since the introduction of feature-based modelling in the 90s. The combination of feature and faceted-based modelling frees engineers from the limitations previously imposed by working with scanned data and other faceted bodies. A world of possibilities is now open to us in design.
Convergent modelling technology gives anyone the ability to perform faceted-based modelling without the need for data conversion. If there is a faceted body from a scan or a JT file, it can be manipulated and changed directly. There are no new commands to learn.
Emerging techniques in design and manufacturing such as topology optimization and additive manufacturing are now easier to use as a result. Designers can manipulate and combine the organic shapes of topology optimisation results with traditional modelling. The combination of the two is critical. Often organic shapes like those from topology optimisation are connected through prismatic structures such as ball joints or pin and socket.
Thus, it is imperative to have both modelling techniques in one model and one part. Additive manufacturing solves the challenge of how to create them.
