Siemens NX Freeform Pro Tutorial - how to use Splines to create Class-A Surfaces (Part 1/2)

Find further free content here: • NX 1899 - NX CAD secre...
The video shows an excerpt from the online training NX FREEFORM SECRETS.
Video Content:
In this video, I will show you hot to create a Studio Spline by poles and through points to create a Class-A surface. You will also learn about the reuirements and which kind of surfaces to start with.
For this example, an 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 (;

really good approach, especially explaining the why ...its barely done in such tutorials

[@AlojzyZyrokompas]

Very informative, thank You.

[@Bizlearn_Siemens_NX_Training]

Use the Studio Surface instead of the Through curve Mesh command to automatically create the possibly simplest surface. This is something I haven't considered ^^

[@MIchaelSybi]

Is it about perpendicular to splines analysis lines conside in the touching area of two splines?

[@travisnguyen1475]

Hi, How can they manufacture freeform surface in practical? can you make video about it. thank

[@Bizlearn_Siemens_NX_Training]

You mean CNC stuff? I don't have a CAM license at the moment.

[@travisnguyen1475]

@@Bizlearn_Siemens_NX_Training No, I mean how can we know the surface is modeled, can be produced in practical? For example a sphere surface is curved in 2 directions, can it convert to sheet metal and flatten?

[@Bizlearn_Siemens_NX_Training]

There are too many possiblities concerning analysis and flattening in order to be able to demonstrate certain things. Maybe I am going to consider some, but the freeform series is more concerning design and analysis than mould creation and manufacturing. The described part is a die cast component, not a typical sheet metal component. Thereby radius analysis might make sense, but deformation?

Please share link of this image,So that I can practise along with your video

[@Bizlearn_Siemens_NX_Training]

I don't have a link of the image. But it should be simple to google it. It's an Audi R8 blueprint

[@watchme3593]

Is there any way to see the result of the modifications you do in real time?

[@Bizlearn_Siemens_NX_Training]

Are you concerning to the time lapse scenarios? I think people should try themselves to modify the poles instead of watching me fine-tuning. I wanna keep the videos as short as possible

[@watchme3593]

@@Bizlearn_Siemens_NX_Training no sorry for my english..I tried to ask if nx can get me a real time feedback of a connected curve when I pull/push a (cv) point. Thank you!

[@Bizlearn_Siemens_NX_Training]

@@watchme3593 of course. You can get a direct feedback after havin the required analysis (e.g. combs)enabled while the creation of the spline. That's what I actually did in the video I guess.

[@watchme3593]

@@Bizlearn_Siemens_NX_Trainingyes but.. you have curvature between 2 curves. When you did a cv manipulation on curve 1, NX gave no realtime feedback on curve 2. So you had to go back and forth few times to make sure you like it.

[@Bizlearn_Siemens_NX_Training]

@@watchme3593 now I understand. it is not possible to show the futural behavior. What you can do is creating one curve instaed of two, which is really hard to do and affords a little more acknowledge of the B-Spline. You have to regard each curvature inflection an get an idea of how many Poles will be required, before you start. It also might make sense then, to create a 2-segment spline with a knot on the transision. Meaning the transition, where curve one is coincident with curve two. You know what I mean?

[@nishadpatel4694]

From where to download this images?

[@Bizlearn_Siemens_NX_Training]

Use the term Audi r8 blueprint on Google search

[@nishadpatel4694]

Thank you sir
It really means a lot to get reply from you
