A spline is a single element that joins a series of points or locations.
Create a natural cubic spline by indicating the locations of the node points. The resulting spline is called a natural spline which means that the curvature is zero at the ends of the spline.
Elements
Create a spline from a series of chained lines, arcs, and even other splines.
Create an optimized spline by duplicating an existing spline, then removing the "unneeded" nodes from it.
Create an elliptical spline.
Spiral Helix
Create a Spiral spline, a Helical spline, or Helical Spiral spline.
The Spline Spiral/Helix dialog box will be displayed.
Surface Spline
The Create Curve dialog appears. Set the dialog, and then select a surface or surfaces.
Create splines associated with surfaces. In some cases the surface spline will be created on (but separate from) a surface. In other cases the spline is created by following features of a surface but is not created on the surface. In most cases these splines will be used as either boundary curves or flow surface curves.
These splines remain separate from their surfaces. Boundary curves are attached to the surface and you can use them for things like surface trimming.
Cross Section
The cross-section spline is created by slicing surfaces (single, multiple, or composite) at defined intervals relative to the CView. The plane of the sections is perpendicular to the CView. When the CView is set to zero, the current view is used.
Surface Intersect
Create a spline along the intersection of two surfaces.
A Cutter Intersect spline is offset from the intersection of two surfaces such that it defines the center of a cutter.
The Select Mill Tool dialog box will be displayed.
Project
Project a spline onto a surface. The spline must be located in space relative to the location of the surface. The projection will be accomplished either normal to the surface or through the construction view.
The Project Spline dialog box will be displayed.
Blend
Create a smooth spline between any two wireframe entities. A dialog box will be displayed for you to enter the fullness factor for the spline ends. The fullness factors determine the final blended spline shape.
Part Line
A parting line is a curve on the horizon of the surface. This is most commonly used to create a parting edge or surface.
Wrap Curve
Wrap curve is a spline created by wrapping a set of chained elements (or curve) around a cylinder.
See the Input wrapping information dialog box.
