Extracting Centerline of dumb cable solid

[NXsupport]

thread561-257837

Hi John ,

Is there any program or journal which would extract the centerline for a cable whose outer surfaces are created by B Surface.. I had one journal file which I had downloaded long time ago from your postings, but that does not work on B surfaces..

NX8.5

Any help is appreciated..

Could you provide an example of something like what you're dealing with?

HI John,

Here is the sample part..

You will need to use the attachment tool at the bottom of the reply window if you wish to attach a file of any sort.

Its a cylindrical surface, but the property of the surface is B Surface..

Iam unable to attach the sample part.. Please help..

Hi Cowski,

If the outer surface is a B surface, the journal does not extract the centerline..

 

[cowski]

In that case, try this one (also written by Frank).
I know this one works for B-surface tubes, I've used it myself.

Hi Cowski,

The tubular surface is not co-planar.. So when I run the program, it gives me some random spline which is not a centerline..

 

[cowski]

Can you post your part file, or a sample that shows the same problem?

I tried to attach the file.. But unable to do so..

Did you use either of the 'file storage' sites who's links are at the bottom of the reply window?

Hi John and Cowski,

Here is the step file..Iam running NX8.5.3

 

[cowski]

The journal I pointed you to expects the tube to be closed in the U direction. Your example tube is closed in the V direction. To change that go to Edit -> surface -> U/V direction..., select the tube face, choose the "swap U and V" option, and press OK. Also, the example tube is a small section of a larger B surface (you probably saw this when switching the U/V directions). To limit the input data to the section of tube shown, go to Insert -> Associative copy -> Face -> single face and for the surface type, choose either "general B-surface" or "polynomial cubic" (either will work). Now run the journal on the extracted face copy.
