NURBS Function

  • Article

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, ...)

Parameters

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.

Remarks

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.
