GetTrim (NurbsSurface) *

Description

Returns a complete data description of a nurbs surface trim. A trim is a nurbs curve list that is projected on a nurbs surface.

Note: This method uses output arguments. C# and some scripting languages (such as JScript and PerlScript) don't support arguments passed by reference. However, there is a alternate version of this method which is considered safe to use with C#, JScript and PerlScript: NurbsSurface.GetTrim2.

Scripting Syntax

NurbsSurface.GetTrim( TrimIndex, [NurbsFormat], IsBoundary, ProjectionType, Count, ControlPoints, [NbControlPoints], [Knots], [NbKnots], [Closed], [Degree], [Parameterization] )

C# Syntax

NurbsSurface.GetTrim( Int32 in_nTrimIndex, siNurbsFormat in_eNurbsFormat, Object& out_vsabIsBoundary, Object& out_vsalProjectionType, Object& out_vsalCount, Object& out_vsaControlPoints, Object& out_vsaNbControlPoints, Object& out_vsadKnots, Object& out_vsaNbKnots, Object& out_vsasClosed, Object& out_vsalDegree, Object& out_vsalParameterization );

Parameters

Parameter

Type

Description

TrimIndex

Long

Specifies which trim must be described.

NurbsFormat

siNurbsFormat

Specifies how the data is formatted.

Default Value: siSINurbs

IsBoundary [out]

Boolean

Specifies whether the trim is a boundary.

ProjectionType [out]

Long

Specifies the projection type of this trim.

Possible Values:

• 0: UV space

• 1: World space

Count [out]

Long

Knots [out]

Array of Doubles

An array of knot values.

NbKnots [out]

Array of Longs

Specifies the number of Knots per nurbs curve.

Closed [out]

Array of Boolean

Specifies whether the nurbs curve is closed .

Default Value: False

Degree [out]

Array of Long

Degree of the nurbs curves.

Default Value: 3

Parameterization [out]

Array of siKnotParameterization

The parameterization factor of the nurbs curve.
