The video shows an excerpt from the online training NX FREEFORM SECRETS.
Video Content:
In this video, I will show you how to create a Studio Spline by poles and through points to create a Class-A surface. You will also learn about the requirements of Class-A. Of course, therefore a bunch of Siemens NX Analysis tool are going to be explained, line reflection analysis, curvature analysis, curve continuity and face continuity analysis.
During each surface or curve creation, the display poles, knots and show combs option are gonna be used and described.
For this example, this Audi R8 blueprint was used, which can be easily found via Google Image Search:

We are going to provide a new tutorial series, concerning freeform modeling. We will focus on the secrets of freeform surfaces like curve mathematics, tolerances etc. The tutorials will cover the design of the Apple Magic Mouse. A huge amount of NX functions like X-Form, Splines, law extensions will be explained. Thereby the required and very important analysis tools are going to be explained in detail as well as the mathematics behind, to help you creating Class-A, or nearly Class-A surfaces. By the way - we offer a Siemens NX online training concerning modeling methods.
Just get in contact (;

First rule of using "blueprints" is - Do not trust them to be accurate. Good video! Been really tempted to use NX full time in place of CATIA.
Excellent content !
Great explanation. Cool example. Thanks a lot.
You're welcome. For me personally, understanding of Class-A helped me to improve my general way of designing (:
The Best ! :)
Could you please tell about class-A surface? From what I read, it's about smooth tangential transitions for consistent reflections.
SOme say it's just tangential, but others it should be G2-G3. As I understand, G@-3 mazatter on long surfaces, where they have a more gradual transition, whereas on short distances G1 will suffice
After I started paying attention, very few cars in real life match this criterion. Most have inconsistency, especially where doors meet the body. I think Bentley will have it, but neither Mercedes nor BMW do
