NURBS Function

Returns a nonuniform rational B-spline (NURBS). This function is used in the E cell in the NURBSTo geometry rows.

Syntax

NURBS(knotLast, degree, xType, yType, x1, y1, knot1, weight1, ...)

Name	Required/Optional	Data Type	Description
knotLast	Required	string	The last knot.
degree	Required	Numeric	The spline's degree.
xType	Required	Numeric	Specifies how to interpret the x input data. If xType is 0, all x input data is interpreted as a percentage of Width. If xType is 1, all x input data is interpreted as local coordinates.
yType	Required	Numeric	Specifies how to interpret the y input data. If yType is 0, all y input data is interpreted as a percentage of Height. If yType is 1, all y input data is interpreted as local coordinates.
x1	Required	String	An x-coordinate.
y1	Required	String	A y-coordinate.
knot1	Required	String	A knot on the B-spline.
weight1	Required	String	A weight on the B-spline.

For every x argument, there must be a y argument; otherwise, an error is returned.

You must specify at least one x, y, knot, and weight argument; otherwise, Visio returns an error.
