Spline

The features available from the Create>Spline drop-down and palette submenus allow you to create various spline types.

The Start and End Condition Menu appears in the Conversation bar frequently throughout spline creation.

Use this feature to create a generic rational B-spline curve by through positions.

Use this feature to create a generic rational B-spline by inputting the vertices of a control polyline.

Use the NURBS Helix function to create a 3D spline that simulates a helix curve with an orientation that you define.

This function allows you to create a constant 2D spiral-shaped curve.

The NURBS From Polyline function allows you to convert polyline entities into splines.

The NURBS Blended function can be used to create a single segment spline that bridges the gap between any two curve entities.

Use the NURBS Chain to Spline function to convert a chain of curves into a single spline.

A list of items relating to the 3D Curve Offset help topic.

The projection of any curve onto a surface will result in a cubic spline entity; regardless of the entity type of the curve projected.

A list of items relating to the Surface/Surface Intersection help topic.

This option will create curves at the intersection of the faces of a body and a plane entity created from the Create Plane functions.

To use this function, follow the steps below.

This function finds the curve resulting from the intersection of two curves projected along specified directions.
