Surface wrapping of streamline body

Surface wrapping of streamline body

Surface wrapping of streamline body

(OP)
I am new to surface modelling and have successfully 'wrapped' most of a streamline body using the 'Studio Surface' function.

I am however running into problems when trying to 'wrap' the nose section.

I am attaching the file and would appreciate any help.

I am not familiar with the different functions available so I would rather just ask here as I don't think it is a difficult problem to solve, but it will probably take me a long time to figure it out from scratch.

RE: Surface wrapping of streamline body

In the attached model I first added a point at the end of the 'nose' (which was convenient since it's located at 0,0,0) and then using Surface Through Curve Mesh and selecting the Point as one of the 'Primary Curves' I was able to create one of the missing quadrants of the nose. I will leave the others to you. Note that the 'Curve Rule' should be set to 'Single Curve' when using this function with this particular model.

Excellent, thank you.

Is there a general rule for when the Through Curve Mesh or Studio Surface or other functions are better suited?

RE: Surface wrapping of streamline body

Most people tend to use something like Surface Through Curve Mesh if there are curves that completely bound the outside of the area to be surfaced.

Thank you very much.

Lastly, if I want to now apply a thickness to the entire surface, what would be the best way to go about it?

RE: Surface wrapping of streamline body

After getting all the surfaces created, first Sew them together. If the surfaces form a complete 'water-tight' volume, a Solid will result and it can then be 'Shelled'. If the surfaces define an 'open' body then you will need to use something 'Thicken' after the Sewing operation.

"Is there a general rule for when the Through Curve Mesh or Studio Surface or other functions are better suited?"
There is a "very simplified" explanation to that...
If you are a surfacing specialist, you will prefer the Studio Surface because it can deliver very clean surfaces if the curves are good.
If you aren't a surfacing specialist, you might prefer the Curve Mesh because it will always deliver, the result might not be that clean but it will create a surface no matter the quality of the curves.

And a more technical explanation,...
The studio Surface will attempt to create a surface where the internal math matches the math of the input curves, if the input curves ( the math) is simple, the the math of the surface will be simple.
The Curve Mesh will always create a degree3xdegree3 surface no matter of the math in the input curves. If and when the degree3 doesn't match the shape, NX will increase or decrease the number of patches in the surface.

Regards,
Tomas
