NX Create an angular dimension on drafting spline

Most of the users don't know how to create an Angular Dimension in drafting on spline curves.

In this video, I have shown how to create an Angular Dimension in two cases: between the "Object/ Spline" and "two Splines". Need to set the selection mode as "Vectors and Objects" in the Angular Dimension dialog box and select spline as an object and specify the vector direction by selecting spline to create angular dimension as required.
