NX Sketch not internalized when creating a contour flange

Even though using existing sketch curve to create a (base) contour flange, the sketch curve is not internalized.

It's even though setting "Make Sketch Internal to Child Feature" in "Modeling" preference.

Reproduced Steps:

1. Create a sketch curve

2. File > “Preferences” > “Modeling” > General > Behavior

  -1. Toggle “Make Sketch Internal to Child Feature” ON

3. Go to Sheet Metal application > Counter Flange

Result : Sketch not internalized

The behavior is due to NX bug and will be fixed in NX 2306 Series.

Workaround : Explicitly execute “Make Sketch Internal” after creating the counter flange.

This issue occurs in NX 2212 Series and lower.
