NX for Automotive and Aerospace Manufacturing – PLM – and 3D Modeling

Commonly called NX, and originally owned by Ross Perot’s company EDS in Dallas, Texas, NX continues to be a very strong and well established leader in the high-end 3D manufacturing world.

Not quite as expensive as CATIA, and 3 times more expensive than Solidworks, NX is more than just a good 3D CAD development product for your engineering drawings.

NX has expanded heavily into the PLM – Product Lifestyle Management segment.

In addition to this, can you guess who comes up as the number one search result in Google for PLM (Product Lifestyle Management)? 

The answer is Siemens Unigraphics NX.

There are many other players out there in this space –

Catia Enova, NxRev for PTC’s Creo, Agile PLM from Oracle, SAP PLM, even Autodesk has jumped on the PLM market with Autodesk Fusion Lifecycle, but none as effective as NX.

PLM is often integrated with ERP – Enterprise Resource Planning.  This is basically knowing when to buy product, for true LEAN manufacturing.

With their tightly integrated approach, NX provides complex product development in a rapidly changing marketplace.

With manufacturing’s need for sophisticated engineering design tools, NX has certainly kept up with the times for delivering the next generation of 3D engineering – modeling – design – and simulation of CAD data.

Once the design is approved, it is now ready for manufacturing.

NX is well suited for direct control of many of the world’s best NC tooling manufactures. In addition to supporting the latest generation of Additive 3D printing. [Hyperlink to 3D print services.]

NX is better geared for the entire manufacturing and PLM – ERP process, more so than the heavy duty CAD designs that CATIA is known to solve.

NX vs CATIA – PTC’s Creo – Solidworks – Solid Edge – or Inventor:

Here is a quick comparison of NX vs CATIA: 

 Both are great design platforms.

Aerospace – CATIA wins hands down.

Automotive – NX has the market share.

(As a side note we did run into point cloud limitations on a complex aerospace part using NX. We ended up finishing the design in CATIA. CATIA is more expensive application.)


PTC Pro Engineer Creo

Creo – Creo’s strength is in very complex assembles.

Imagine an entire John Deere tractor as a single 3D model that contains every nut and bolt into one file.

That is where Cero’s greatest strength lies. Here Creo and NX are neck and neck.

Creo and NX are about the same cost.


Dassault Systems Solidworks

Solidworks – Almost an apples to oranges comparison. Both are very good design platforms.

Solidworks is easy to use for 90% of the 3D design work.

NX is more geared towards an enterprise solution, vs. Solidworks which is geared towards an individual user approach. NX is 3x the cost of Solidworks.

Solid Works is an older product line, starting about the same time as NX.

However Solid Works, does not have the market share and control as NX. 


Inventor Autodesk Logo

Inventor – like Solidworks, this is almost an apples to oranges comparison.  Inventor has really never taken off, even with the marketing clout of Autodesk.

Inventor is also not a very strong 3D design tool. It is very limited (= almost nonexistent)and has problems with free form design (think of airplane wings). There are also severe limitations with point cloud sizes, and more.

Granted NX is 4x the cost of Inventor, Inventor is not even in the same league as CATIA, NX, Creo, Solid Edge, and Solidworks.

Siemens NX hot-features : based on CAD / CAM Services real world design experience:

  • A very convenient search of a required feature. UI: Similar to SolidWorks, just more fluid. Useful selection filter – easy to pick sketches, dimensions, and so on.
  • Comprehensive set of features and functionality.
  • Synchronous modeling, perfect analysis and simulation.
  • NX handles huge assemblies well, comparing to PTC’s Creo.
  • Full featured CAD-CAM-CAE solution
  • Featured-rich PLM than can track down a part to individual customer.
  • Used mostly in Automotive and Aerospace industries
  • Price: more expensive than SolidWorks but cheaper than CATIA
    • Focused more on production process than creativity

There are few cons as well.

  • Less installs than others, smaller online community.
  • NX is not user friendly. Even after us knowing how to fully use in real life production environments, some of the most complex and full featured 3D CAD software systems known to man; we found NX hard to use. To us NX has a complex and expensive learning curve.
  • NX falls behind in designing of complex surfaces.

Most manufacturers require their CAD service providers to produce engineering CAD files in the same software they use.  Thus, CAD/CAM Services will continue to use and specialize in NX for many years to come.

CAD Software Systems are Proprietary.

Many of the other CAD software systems have their fair share of pros and cons as well.

All of the CAD systems are proprietary, and none of them like to transfer data to other CAD systems.

One big reason it is difficult to transfer data is that, most all CAD software systems use a different 3D kernel for their 3D design engine.

Think of it this way, if you know that CAD software company X spends millions of dollars a year updating their CAD software, do you think the CAD software developer wants to give you a way to export your data to a competitive CAD system?  Absolutely not.

NX is one of the best full-featured CAD systems in the world today.

NX has spent millions on the development and integration of PLM data to work with engineering data, and this huge.

Auto manufacturers spend millions of dollars on any recall. So having an intelligent well-engineered PLM system, overrides the need for a higher end 3D CAD system. The majority of NX users simply do not need the higher end 3D design tricks.  To this user, business intelligence is more important.
