Boundary Blend Control Point Parameters
The following parameters for blending curves are available, depending on the type of curves selected:
|
Case
|
Parameter
|
Description
|
|---|---|---|
|
Any
|
Natural
|
The selected curve set is blended using the original curve parameterization.
|
|
Any
|
Arc Length
|
The selected curve set is blended using arc length (constant speed) parameterization in which points at the same fraction of length on each curve correspond to each other.
|
|
Only splines with an equal number of interpolation points
|
Point to Point
|
Each corresponding set of points is connected to create the surface.
|
|
Any curve, curve chain, or composite curve having an equal number of entities or segments.
|
Piece to Piece
|
Each corresponding set of curve pieces is blended to create the surface.
|
|
Two tangent continuous curves
|
Developable
|
Each corresponding set of control points is blended so that the surface can be flattened.
|
 |
There might be no visible difference between the natural and arc length options in the following cases:
• Curves that are lines or arcs, whose parameterization is arc length by default
• Curves whose parameterization is close to arc length
