What is NX Open?
NX Open is the official application programming interface (API) provided by Siemens NX, designed to help engineers and developers automate, extend, and customize the NX software environment.
Using NX Open, you can write code in C++, C#, Python, or Java to:
-
Automate repetitive modeling and drafting tasks
-
Create custom dialog boxes and user interfaces
-
Build intelligent design templates and product configurators
-
Integrate NX with external tools like Excel, PLM, or ERP systems
NX Open gives you direct access to the underlying functions of NX — allowing you to create tools that boost productivity, ensure design consistency, and streamline engineering workflows.
Why You Learn NX OPEN?
High Salary
“CAD Design Engineers with 4 to 5 years of experience typically earn a CTC between ₹5 lakh and ₹10 lakh. In contrast, CAD Developers with similar experience can secure salaries ranging from ₹20 lakh to ₹30 lakh.”
Good Demand
“While CAD Design is a well-known skill among mechanical engineers, there is intense competition for design jobs. On the other hand, CAD Automation & Customization is a niche expertise, with only a few engineers.”
Easier To Learn
“While CAD Design is generally easier to learn, CAD Automation & Customization can be more challenging. With our extensive experience in this field, we aim to simplify the process for you with our step by step training.”

FAQ's
NX Open is an Application Programming Interface (API) for Siemens NX CAD CAM CAE Tool. With the help of NX Open API Programming we can easily create custom functions to do some tasks in NX automatically and that will save lots of time and improve quality of delivery. Please watch some of our YouTube videos Here for more clarirty on this.
NX Open programmers will get several times more salary because they create Automation tools that can do the work which cannot be done by even many people without that tool. Please watch the video at the end of this page which explains in details.
Anyone who has good knowledge on NX CAD tool and VB.NET or C#.NET programming language concepts and also NX Open API.
Mechanical Engineers or Computer Science Engineers are the ideal candidates.
It is super fantastic. Many companies are recruiting in 2021.
We have trained many people and they got very good placement without any previuos programming experience.
One student got even three offers from three different companies with CTC 6, 6.5 and 8 lakhs per annum.
We are the best training institute for CAD Automation & Customization.
Our mentors have decades of internation work experience.

We have lot of success stories and prooven track record.
We do have job guaranteed course which are little expensive than regular courses.
Job guaranteed courses are not for all students but only for selective students and it comes with lots terms and conditions.
Because getting job is lot depends on your ability and how how much effort you put practicing this.
Yes. That is an advantage for you. You can fully utilize your design skills and CAD tools experience.
You can easily judge and take right decision on what to be automated and what is the value of that automation.
So, You can lead the team of design engneers as well as developers.
You get certificate with grading or % of marks in it. We ealuate your skills at teh end of the training and based on that we will give you grade.
.NET is widely used for CAD Customization.
.NET is little easier compared to C++.
You can use the same skill to customize any CAD tools like CATIA, NX, AutoCAD, Creo, Solidworks, Inventor, Revit etc.,
C++ is good for CATIA CAA Customization and Creo Toolkit Customization.
Yes and No.
The programmign concept you learn in the first half of the training is common for all CAD customization.
The CAD API you learn in the second half of the training is specific to one particular CAD Tool.
So, to work on all CAD customization you need to learn different API (Application Programming Interface) specific to that particular tool.
But if you know one API well then you can learn other by yourself with little effort.
