Creating B-Spline by Specifying Control Points
B-Splines are those created by connecting specified point arrays with a smooth spline. When creating a B-Spline by specifying control points, specified point arrays will be control points, and a B-Spline will be created within the range of these points.
- Point [Spline] on [Shape] menu, and click [B-Spline Curve (Control Point)].
Then you will be able to create a B-Spline.
- Specify whether a B-spline is closed or not closed in [Spline Type] on Command Window.
- Click point arrays in order to create a B-Spline on the drawing.
Clicked points will be specified as control points for a B-Spline.
- Press Enter key on the keyboard, or click on the toolbar on Command Window.
Specifying point arrays will be complete, and a B-Spline will be created.
