Complex wrap around revolution surface
Complex wrap around revolution surface
(OP)
Greetings everybody!
The file is attached to the post. Is it possible to accomplish this task in NX8.5? What I need to do is to 'wrap' the curve modelled in the second sketch around the revolution surface. This is a real life task, it's actually represents trajectory of a windind rod bend around the parts in an assembly.
Should it been a simple cone, there would not be a problem, because simple Wrap would do. But the problem is that the target surface is complex.
My wild guess is that Law Curve could help here. But I'm not that proficient with this tool to be sure. Any help is appreciated.

RE: Complex wrap around revolution surface
The approach I took (when I've encountered similar situations in the past, I've used this approach with some success) was to approximate your surface model with something that I COULD wrap a curve around, in this case a Cone, and since your model was already mostly a cone, I used that face and just extended it enough to cover the entire model. I then had to do some work to get a curve representing your sketch tangent to this new face so that I could perform the Wrap operation, which I then simply projected along the face normals of your surface model, which resulted in the Green curve that you see. Now, as I said, I know it's not perfect, but it might just be close enough.
Anyway, take a look at the model and see what you think. You can follow my logic by looking that objects that I created and I think you will see how I approached this and that it might just be good enough

I think it's cunning, but the result is not exact enough at the wider side of the surface.
Is there any other methods? Again, can Law Curve be utilized here? Some other ideas?
