About the Founder: Leopold Rott
20 years of NX expertise – taking you from active design straight to project success.
"A stable CAD model is no accident; it is the result of the right methodology. My goal is to ensure that your software works for you – not the other way around."
The founding of Austrian CAX Services is the natural evolution of two decades of passion for engineering processes. I offer more than just technical know-how; I provide the profound insight gained from 15 years spent directly at the source of Siemens NX.

The Evolution of Expertise: Practice over Theory
My career is driven by the conviction that you can only provide CAD consulting if you have felt the "pain" of the users yourself.
-
5 Years at the "Front Line" of Design: In my early years as a design engineer, I learned what it means to juggle complex assemblies under tight deadlines. I know the reality of unstable constraints and unpredictable error messages just before a deadline. This time sharpened my focus on pragmatic and resilient solutions.
-
15 Years at the Heart of Siemens NX: For the last decade and a half, I worked directly for Siemens Industry Software in Training and Consulting. During this time, I actively accompanied the evolution of NX – from early versions to today’s high-end system. I have supported numerous companies, from specialized SMEs to global corporations, in optimizing their workflows.
Why Austrian CAX Services now? After 15 years in a corporate environment, it is time for a more direct path. As an independent founder, I offer you this concentrated insider knowledge unfiltered, flexibly, and with an absolute focus on practical application.
What to expect from me (and what not to)
You won’t find standardized "PowerPoint training" here. I stand for methodological competence that starts where the manual ends.
-
Applied Knowledge: 15 years of working for the software manufacturer itself. I understand the logic behind the software and know exactly how functions work – allowing me to immediately identify why a model holds up or why it breaks.
-
Problem-Solving instead of "Click Acrobatics": We talk about WAVE Control, Selection Intent, Load Options, and Model-Based Definition (MBD). We optimize your data structure to ensure it is perfectly prepared for downstream processes like simulation or manufacturing.
-
Speaking Your Language: I speak the language of your engineers. My focus is on reducing frustration and increasing efficiency, so your team can focus on what matters most: outstanding engineering.
My Promise: Security for Your Processes
Although Austrian CAX Services is a young company, you are not buying into a "probationary period." You are securing the expertise of a consultant who has resolved countless complex project situations across the industry.
I invite you to benefit from this competitive edge. Let’s take your CAD methodology to the next level – stable, high-performing, and future-proof.
