NX Convergent Modeling: 

Product designers and engineers who need to incorporate facet data from workflows such as scanning, 3D printing and topology optimization into their 3D modeling environment benefit from applications that are based on Convergent Modeling technology.

Convergent Modeling provides a unified 3D modeling capability on combinations of facet and B-Rep data. These two data formats have different geometric characteristics and as a result, one format has often been better suited to a given application than the other. Facet data is characterised by triangular meshes which approximate surfaces and tend to generate larger data sets. Applications that use facet data include digital mock-up, gaming and animation. B-Rep data is characterised by mathematically defined surfaces that represent accurate, closed (solid) volumes using smaller data sets. Applications that use B-Rep data include 3D modeling for engineering and manufacturing.

A proliferation of facet data in high growth areas like 3D scanning, topology optimization and 3D printing means that design engineers often need to move facet data into 3D modeling systems that were designed for B-Rep data. Convergent Modeling Technology enables 3D product modeling on both data sources in a single environment, while eliminating the complexity, error and delay of converting between the two.

NX Realize Shape:

This solution give designers even more control over geometry modelling to produce products with highly stylized shapes or complex surfaces. NX Realize Shape is based on sub-division modelling, a mathematical approach to creating 3D geometry with smooth flowing shapes, pioneered by the entertainment industry. The tool is seamlessly integrated with NX which helps shorten product development time by eliminating the multiple steps associated with using separate tools for freeform design and engineering development.
