What's new in NX?

New in December 2022

Powerful new capabilities for CAM programming, additive manufacturing, CMM inspection programming and more are available in NX 2212. The new, advanced functions, such as automated programming, new machine strategies, AI-powered processes, and better shop floor connectivity help manufacturers boost productivity. Here are some of the major new enhancements in the latest release of NX CAM, AM and Design.

Adaptive Roughing

The new 3D Adaptive Roughing operation, which replaces the Adaptive Milling operation, enables faster programming and shorter machining cycles. The bottom-up cutting strategy can be used to efficiently remove material between cut levels by re-cutting the walls at each cut level by stepping upward. The other enhancements include more accurate tool holder collision checking, thin wall option, and flat surfaces machining using the adaptive pattern.  

Guiding Curves

Guiding Curves Mid Pass Patterns provides new cutting strategies that define the guiding curves automatically. It uses the medial axis defined by the topological center of the cut area. Previously, users had to manually select guiding curves. The new strategy provides flexibility to create passes offset or morphed using the medial axis, enabling programmers to create the most efficient toolpaths for any part. 

Face Mill Mid-Pass 

Using the new Face Mill Mid-Pass operation, programmers can quickly create toolpaths on flat faces with complex shapes, such as mating faces on machinery casings. Just by selecting the face, you can create intelligent toolpaths that can ignore or cut around the holes, as well as define an offset. It can even show the uncut material using the In-Process Workpiece (IPW) technology, enabling programmers to rapidly create optimized toolpaths.


Turn-milling, a Rotary Milling capability, is a new cutting strategy for cylindrical and conical parts with feature obstructions, such as bosses and split seam flanges. It simplifies programming of parts with symmetric and eccentric surfaces. Advanced settings, including axial and radial limits, engagement types, and cut sequencing help you create optimal toolpaths for your applications. You can program both roughing and finishing operations using many tool types, including indexable, solid, ceramic, carbide, round, and wiper tools. 

Turning Threads IPW

Turning Threads IPW display enables realistic 3D material removal for turning threads during simulation such as the G-code-driven simulation in NX. The detailed depiction of the machining process enables programmers to validate thread operations quickly and accurately. 

AI-assisted programming

The AI-assisted programming in NX CAM has been further enhanced in the latest release. In addition to assisting in the creation of new operations, the AI technology now helps you with editing operations. Learning from your best programming practices, NX predicts the most probable used parameters, presenting a minimal set of parameters, accelerating the programming process and ensuring repeatability. 

NX CAM Wire EDM Advanced

The new NX CAM Wire EDM Advanced add-on, introduced in the October release, delivers industry-leading capabilities to program a wide range of wire EDM machines. It offers a direct access to machine tool technology databases for all common wire EDM machine tools, such as Agie-Charmilles, Mitsubishi, and Fanuc. Visit this blog to learn how this new module helps you quickly generate optimized operations that can increase the overall cutting efficiency.

NX CMM Inspection Programming

The CMM inspection programming enhancements provide more automation and integration with the CNC programming phase. Using the Automatic Scanning operation, you can create scanning paths automatically without using manually created curves. This not only helps reduce the programming process, but it helps you utilize standardized inspection strategies. 

NX On-Machine Probing

NX  On-Machine Probing is a brand-new module in NX. This interactive capability offers a simple method to use machine cycles for probing on machine tools.​ You can execute and create machine cycles all in one operation, while creating measurement statements using feature-based methodology. 


Print Marking

The new AM capabilities include the ability to create embossed and debossed print markings for all printer types and manufacturers. Using the new Boolean build tray attribute, you can choose desired operation for different 3D printers. 


The new drag-and-drop methods for adding parts to the build tray speeds up the AM preparation process. You can now drag-and-drop part files, STL files, or assembly files into the build tray and then easily define the part position. 


The multi-axis enhancements in NX Additive Manufacturing include new material build-up methods that adds materials along the axis of rotation of cylindrical parts. This new, axial method complements the helical build-up strategy, providing more flexibility and addressing the needs for wire arc additive manufacturing (WAAM).

Freeform Additive Buildup

The Freeform Additive Buildup operation has been enhanced to control the tool axis, including tilt and lead angle. This is particularly useful to avoid situations when the laser is normal to the surface, avoiding damages of the sensors. 

Printer Support

Printer support is expanded with further support for EOS printers and added support for ARCAM hardware. 

Topology Optimisation

Key improvements of this release:

  • Major PR fixing and solution quality improvements
  • Optimizer solver enhancements/ upgrades for Vibration analysis and Analysis constraints
  • New manufacturing constraint: Fill from direction 
  • New analysis load: Acceleration loading
  • Auto-detection of face-to-face and body-to-body connections

Core Modelling

There are several new features:

New Pattern Functionality

An area with new functionality revolves around Sketch Pattern enhancements. The new Pattern Relation Finding allows users to control which instances participate in modifications. You can set finding scope during pattern creation, whilst relation scope can be edited in the Pattern dialog. Those older sketches? Don’t worry, these can all be renewed to use the new functionality.

Sliding relations in the sketch solver

The sketch solver now finds ‘sliding relations’, laying the groundwork for improved design intent documentation. Most relations are found on touching curves within a sketch. If one curve ‘slides’ off another during modification, the relation can be lost. Additional improvements to the sketch solver prevent this from happening.

Further improvements are:

  • Thread Propagation to Multiple Bodies
  • Move Object
  • WAVE Linking Material Properties

BIM (Building Information Management)

NX for Building Information Management is an advanced 3D parametric design tool that enables designers too quickly create and document buildings.

User Interface Customization

Siemens customized the user interface and streamlined it to enable efficient creation and editing of complex building structures. You can make use of the BIM Design Navigator to quickly switch between levels and edit BIM objects, whilst components and features will also be visible and editable in a single navigator.

Elevation and Grid Lines

You can now create and edit Grid and Elevation lines by using an intuitive sketching environment. In addition, lines can be customized to adhere to various industry or customer standard display types. Easily reference Grid and Elevation Lines when positioning structural elements such as walls, columns, floors and ceilings.


For the December 2022 release, we have focused on load performance, enabling the ability to visualize larger amounts of data and reduced files sizes using JT Moniker Technology. 

  • Optimized for large feature counts​
  • Reduced load time and creation of associative features (between 1.2x – 25x)​
  • Reduced PRT file sizes by on average 5.7%
  • Removed the dependency on the KF Framework
