Siemens PLM Software has released the latest version of its PLM NX software, is a major release with significant new functionality in all areas of the product. With the release of NX 11, Siemens PLM is still finding areas for innovation to enhance an already breathtakingly mature system.
Backbone updates
NX has been through a rework of its user experience in recent years. The result is a UI that is clean, fresh and clearly laid out.
While this hasn’t been tinkered with for this release, there are a few updates to the underlying architecture that apply to almost every user, so let’s take a look at those first.
The biggest area, something that NX users might already be aware of, is that the existing built in photo realistic rendering engine (or renderer, if you prefer) is being replaced with LightWorks’ Iray.
While the previously integrated tools were good, this takes things to the next level. All of the progressive, physically based r
Much of this drive has been from the interest in additive manufacturing, but to say that this is the key application for it would be wrong.
The ability to gain guidance as to the best structure to solve a particular set of engineering performance criteria is incredibly beneficial. And while topology optimisation has historically been something conducted separately from the workhorse CAD system (such as SolidThinking Inspire), this is now changing.
Interestingly, Siemens is starting to build such tools into NX based on the technology from NYC-based startup, Frustum.
The new NX Topology Optimisation module follows an expected workflow for these types of things. You define your design space, in terms of features that need to be maintained, a geometry area that will become the focus of the optimisation (shown in the image below as transparent pink), any keep out areas (in yellow in the same image), then define the boundary conditions in terms of loads, constraints, materials and such.
Finally, you then define the parameters for the optimisation process, as a mass target (that’s why you define a material rather than using a percentage reduction).
You can also define any areas of symmetry (the image above has one) and then, finally, the speed/resolution of the process.
The end results are what we’ve come to expect from topology optimisation these days — a mesh that’s organic in shape and which provides the idealised structure to solve the given design challenge.
What’s interesting is that we’re now starting to see the next generation of these types of tools.
While Frustum’s tools provide a much cleaner surface, other tools such as solidThinking handle it differently but the end results are similar, as you’ll learn later on in the magazine.
When combined with the new convergence modelling tools, you’ve got a fascinating environment for design and development of additively manufactured components that are incredibly lightweight.
However, that said, there’s also, of course, huge potential for using these types of tools to guide the design of more traditionally manufactured components as well. Although it’ll be a slightly more convoluted process to take that mesh and use it as reference to build a more traditional model that can be cast, machined and/or moulded.
Flattening & forming
The last few releases of NX have introduced a range of industry specific tools, particularly in aerospace.
Rib and stringer design was the focus for the NX 10 release. This continues in NX 11 with some work being done on joggles where stringers meet ribs and, in particular, adding flanged cutout to ribs.
This release also features flattening and forming related tools that are focussed specifically on double curvature forms — regardless of manufacturing method or material used, e.g. can be fabric or plastic or metal.
For some time NX’s flattening tools have enabled users to take a complex surface or set of surfaces and flatten them out for blank development etc. But these were built on a pretty heavy CAE based approach so the Siemens team set out to create a designer level tool.
The new set of flattening tools eschew this CAE, finite element approach, it uses a non-material based minimum deformation approach to flattening. This gives you almost exactly the same result but in a fraction of the time. We’re talking seconds rather than hours to set up.
To use it, you select the surface or surfaces you want to flatten, pick the point in space to flatten to, pick a primary direction and — pop! — you’re done.
There are then tools that allow you to conduct some analysis, such as distortion mapping that shows where pinch points or tears might occur.
What’s also interesting is that some additional features have been built on top of this new approach. For example, you can now add in another sketch to the flattened form (perhaps for a cut out, to add strengthening features or additional fibre lies) and have that automatically reflected back into the original formed model.
This is also complimented with the new tools that allow you to project a 3D sketch onto a surface (to cut out a feature) and have the cut maintain the surface it is cutting (rather than projecting from a single plane vector) — think cutting features for windows or other inlets/outlets in a fuselage.
NX 11 extends the rib design tools into sheet metal design — Flange cut out (applied to flat pattern) and Lightening Cut out (flange with stiffening flanges to specified angle). You can also build a plane to reference surfaces — to outer mould line (OML and IML).
Finally, it’s also worth mentioning that there’s been some reconfiguration of the product offerings. You’ll now find that all of the aerospace sheet metal related tools are being rolled into the advanced sheet metal module meaning that all those tools will be in one place, rather than two separate cost options.
Variable offsets
It’s not often that we highlight a single new feature in a design system, but this one struck me as being worth the effort as it shows how intelligent these mature systems are becoming and how hard the users are pushing development.
So, let’s take a look at Variable offsets.
Consider taking a single set of surfaces like those found on the outer skin of a car door. Then consider the matching internal surface that’s welded to it.
That internal skin is very different. It has strengthening features that are required to reduce the weight (or lightweighting as it’s commonly referred to) as well as all manner of other features to provide access and mounting positioning for the various hardware and
panels.
Designing that inner surface is a complex business and is typically defined in terms of offsets from a single surface outer. The new variable offset operation in NX 11 allows you to create the basic forms and offsets, in specific regions, in a single feature.
3D drawings & PMI
The final update we’re going to talk about for NX 11 relates not to modelling or drawing creation, but rather a combination of the two.
PMI (Product Manufacturing Information) or 3D annotation is a topic that has been bubbling away for a good few years now.
Some industries have ignored it while others have taken it on board.
Part of the issue is that in many cases you’re creating the MPI directly on the model, then pulling that information into a 2D drawing. Very rarely is it done the other way round.
That makes sense when you’re creating data from scratch, but if you’ve got years, if not decades, worth of legacy data, the process of taking that vital GD&T (Geometric Dimensioning and Tolerancing) back into your 3D model is both time consuming and painful.
To get around this, NX 11 allows you to have a product model with associated drawings and the key GD&T, but then uses some clever tech to apply that drawing based information back to the 3D model.
