In NX 12 the Modeling Preference 'Treat Degree 1 Spline as Polyline
' is ON
by default. As a result the Extrude command will create a Convergent body (rather than a typical Analytic body), if the section being extruded contains a curve/edge that is a Degree 1 Spline.
In NX 12.0 and 12.0.1 the user can turn off the 'Treat Degree 1 Spline as Polyline
' preference (located under 'File - Preferences - Modeling - General/Convergent
'). However, there is no corresponding customer default to control this setting, therefore it will be ON at the start of every new NX session.
In NX 12.0.2 there is a customer default to set this preference, under 'File - Utilities - Customer Defaults - Modeling - General - Convergent
'. The 'Treat Degree 1 Spline as Polyline
' preference is ON
