Better design starts with better software.

The latest release of NX software delivers a robust set of new tools and significant enhancements to existing
functionality. The goal is to help you design, test and manufacture your products quickly and with fewer errors than ever before.

NX 11 introduces capabilities for convergent modeling, rapid manufacturing, with improved annotation, drafting and documentation, and rendering. Active Workspace in NX 11 is built around these items to provide seamless access to PLM capabilities right within NX.

The following article explains the new modeling technology "Convergent Modeling".

Convergent Modeling

Convergent Modeling is a new modeling technology in NX 11.

It allows the designer to work with facet geometry in his usual design environment.

This enables merging of facet and B-Rep geometry, which offers completely new ways in the design process.


When importing STL data, until now, there were only two possibilities for output types:

  • NX facet body
  • JT facet body

The new Convergent Modeling technology provides a third possibility:

  • Converging

In contrast to the previously known import of STL data, a "Convergent Body" is generated by selecting "Convergent".

With this body, work can be continued.
Boolean operations as well as offset functions are supported.


The surface of a converged body can also be subdivided such as B-Rep geometry.

This surface can be used for further design engineering.

The generated geometry represents the surface topology of the tapped area.


The converged body can also be used for trimming, in order to adapt a design to the converged geometry.

The goal is, that users do not notice a difference whether he is working with a STL or a self-created body.

Thus, Convergent Modeling provides an unprecedented flexibility in design.
