Curve Flowline ribbon bar
|Use this ribbon bar to create flowline curves on surfaces. For NURBS and parametric spline surfaces, exact curves are created. For all other surface types, chord height, tolerance-curve fitted cubic NURBS curves are created.
The options in this ribbon bar determine the number of curves to be created and how closely the curves fit the surface on which they are created.
Choose the curve quantity and quality and select a surface in the graphics window. As soon as you select the surface, the curves are created and remain live. While the curves are live, you can edit both the number and the surface fit of the curves.
Note: AutoCursor is unavailable during the use of this ribbon bar.
F – Flip
Q – Curve quality
C – Curve quantity
P – Apply
O – OK (fixes live entity and exits function)
