1. What is Specify Origin Curve?
In NX 12 ‘Specify Origin Curve’ option was introduced in the section group of the extrude command. For extrude or revolve when an ‘Open’ section is selected then the origin curve will be either the first curve or the last curve. But in the case of the ‘Closed’ section, there is no way to tell the origin of the curve. This option is helpful to specify the origin curve in the selected section and the direction of the first curve of the section is shown by a direction vector.
This option is useful in the case of Replace Feature mapping operation and it helps to organize mapping visually which results in stable feature updates after feature remapping.

2. How to Enable ‘Specify Origin Curve’?
In the NX 1969 MU (1953 Series), A new customer default was introduced as ‘Show Section Curve Flow Direction’. By default this customer default setting is disabled and it determines whether or not the curve flow direction and origin curve controls are available for section-based feature commands such as Extrude. (Flow direction and origin are always available for flow-sensitive features such as Swept.)
Go to File > Utilities > Customer Defaults > Modeling > General > General tab > Show Section Curve Flow Direction.
Enable it and Restart NX so that specify origin curve option will be available within the section group of the extrude command dialog.
