How to extract this kind of centerline? 1

If you need the centerline constructed like a spline for some other modeling reasons, then you can do this:
1. open and then use last journal on this site. This journal will create a spline as the centerline of the selected face. It will also calculate the length of this spline.
2. use the option for creating a centerline, as described from GTAC team: With both options, you will get a spline/curve, that you can use later for some moedeling.
I have received those two options yesterday, when I was asking about creating a centerline in a parasolid or step file. I have been asking this on Siemens PLM Community.

Extract virtual curve (EVC) works great for blend faces, but not so well for tubes. If the tube is bent along an arc, EVC will return the bend centerline but never returns the tube centerline.

Hi SvenBom,
Thanks for the introduction to a vast knowledge of NXOpen behind it. I am fascinated. I have also glimpse through the code at nxjournaling.com by Cowski, tried his centerline simple demonstration. But I will just update my progress result with that code as below.
It seems the result is unexpected probably due to my tubes are hollow and there is an intersection which is not tangential.
The GTAC method works fine, but requires manual effort.
Anyway, thanks for giving my a direction.

Credit where credit is due: the code that creates centerlines on B-surface tubes was written by FrankSwinks. I just made a few simple edits to the code in the thread referenced by SvenBOM.
