the rise of Siemens NX and demise of PTC.. 4

[Regret]

Hi

As a chartered engineer (PE) experienced in the design of complex castings and assemblies in automotive powertrain, I have contracted in many corporate OEMs over the past 20 years (BMW, Caterpillar, Cummins to name but 3). I have used Pro/E-Creo, CATIA and NX, and an experienced and qualified in all three.

I have never met ANYONE competent and experienced in all 3 who does not prefer Pro/E-Creo and who does not despise NX. CATIA dividing opinion.

Why then, is PTC losing out and NX gaining?..especially when you consider NX was so bad they nearly vanished under EDS, and NX 9.0 us essentially the same as NX 2.0...

Are Siemens giving NX away to corporate customers?

One thing is certain. No one is benchmarking software, and decisions are not being made by those competent to do so.

So my question is why is NX on the up? Is it on the up?

Allow me to introduce myself: user experienced in all the above and one who prefers NX.

In terms of modelling capability, there is no contest. NX is by far the most capable. The reason most people don't know this is because most people are not knowledgeable enough to understand why this is true.

I said in the original mail I have used NX since NX 2.0 and currently use NX 9.0.On complex castings.I am formally trained and have over 15 years commercial experience in NX.

Please justify your answer. I will start off by asking you to explain how sketcher constraints, the basis of parametric modelling are in any way favourably comparable to CATIA or PTC?

Please qualify your answer with your commercial experience of all 3, otherwise your answer will lack validity.

And try to answer the question I originally posed.

Welcome to the forums, Regret. As a new user, you should probably post this question in a relevant forum, but try not to "double post" across multiple forums. Your better options would have been to post in either:

forum554
forum561
forum560

I don't see how posting your question in a SolidWorks forum will yield you the validity of opinion you are seeking.

"Art without engineering is dreaming; Engineering without art is calculating."

Have you read faq731-376 to make the best use of these Forums?

 

[Regret]

I agree. I didn't realise this was a Solidworks forum... I posted it for general comment. Hopefully by experienced engineers without an axe to grind.

Still thrashing about with the basics, I see. 15 years? Really? Sketch constraints is what you're carping about?

My resume? You've undoubtedly seen my work before. Some of my early UG and Pro/E work below.

Can Creo allow you to change the degree of a surface up or down from 3rd degree to 33rd? Do you even know what this means? Have you ever been in a position where it actually matters?

Does Creo allow surface editing by actual defining points or poles? No. Can you literally turn one surface into a different surface that becomes a clone of a face and blends in seamlessly when united?

Does Creo allow one to adjust knit and trim tolerances for individual faces?

As far as CATIA goes, I have discovered problems that even the developers were unaware of, things that were written off as "translation bugs" that were actually problems with CATIA's core kernel.

So... what's on your resume.
