Summary


Details

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.



Solution

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 by default.
