Wrap/Unwrap Curve

Pioneer

Hello guys,

I need to perform wrap operation on a cross section which has fillet in it. (Kindly see attached)

Wrap curve option fails since the entire curve is not developable about a common plane.

 

Is there anyother options to perform the same in NX ?

 

Thanks

Hello Sathya,

 

im sure that this will solve your problem, its including developable curve/surface operations which is the same thing you looking for:

Based on your description, I am not sure why you are having a problem doing this. If you are trying to wrap the rectangular shape about the path you show in the image, the following should help:

  • First of all, the wrap/unwrap command requires sheet or solid faces as the target. So you need to extrude your path in order to define the necessary faces for this to work.
  • To ensure that the resulting warpped shape is correct, the rectangular sketch needs to be defined on a plane tangent to the cylindrical face (bend).
  • Other than that, this should just work. I hope the video below uploaded correctly. You can take a look at what I did.

(view in My Videos)

I hope this helps.

thanks @Abeinjapan for the reply.

 

Unfortunately I could not get it done. Could you share the model which was used to create the video.

 

thanks !

Thanks Abeinjapan.............

It works well with extrude...

@sathya Now I understand your problem. Wrap curve does not support toroidal faces. Within analytical surfaces only cylindrical, conical or planar are supported. You will need to file an ER to have toroidal faces supported as well.

You might be able to do it with global shaping. See @BenBroad's example file here:

Hi @cowski1,

 

I already tried global shaping but I didn't suggest using the command as I didn't like the results I was seeing (based upon my interpretation of the geometry in question).  @sathya, it would help to know about which axis the section is being revolved around - can you upload a 3D screenshot showing the curves in relation to the body?
