KeyCreator Prime / Curve / More / SplineSplineSplineThe features available from the Create>Spline drop-down and palette submenus allow you to create various spline types. Start and End Condition MenuThe Start and End Condition Menu appears in the Conversation bar frequently throughout spline creation. NURBS Through PositionsUse this feature to create a generic rational B-spline curve by through positions. NURBS Control PositionsUse this feature to create a generic rational B-spline by inputting the vertices of a control polyline. NURBS HelixUse the NURBS Helix function to create a 3D spline that simulates a helix curve with an orientation that you define. NURBS SpiralThis function allows you to create a constant 2D spiral-shaped curve. NURBS from PolylineThe NURBS From Polyline function allows you to convert polyline entities into splines. NURBS Blend CurveThe NURBS Blended function can be used to create a single segment spline that bridges the gap between any two curve entities. NURBS ChainUse the NURBS Chain to Spline function to convert a chain of curves into a single spline. 3D Curve OffsetA list of items relating to the 3D Curve Offset help topic. Project to SurfaceThe projection of any curve onto a surface will result in a cubic spline entity; regardless of the entity type of the curve projected. Surface/Surface IntersectionA list of items relating to the Surface/Surface Intersection help topic. Body/Plane IntersectionThis option will create curves at the intersection of the faces of a body and a plane entity created from the Create Plane functions. Using the Body/Plane Intersection FunctionTo use this function, follow the steps below. Curve/Curve ProjectionThis function finds the curve resulting from the intersection of two curves projected along specified directions.
