AverageLocalReferenceFrame (Geometry1D)

Description

Get the average normal of given 1D geometry

Scripting Syntax

Geometry1D.AverageLocalReferenceFrame( compIdxArray, XAxis, XAxisValid, YAxis, YAxisValid, ZAxis, ZAxisValid )

Parameters

Parameter

Type

Description

compIdxArray

Array of Integer values

An array of indices of 1D geometry

Possible Values:

• 0 <= compIdxArray(i) < Number of 1D geometry: Each index in the array must be valid

XAxis [in/out]

SIVector3

Upon return, contains the X axis of the average local reference frame of the given 1D geometry

XAxisValid [in/out]

Boolean

Upon return, contains TRUE if the X axis of the reference frame is valid, else FALSE

YAxis [in/out]

SIVector3

Upon return, contains the Y axis of the average local reference frame of the given 1D geometry

YAxisValid [in/out]

Boolean

Upon return, contains TRUE if the Y axis of the reference frame is valid, else FALSE

ZAxis [in/out]

SIVector3

Upon return, contains the Z axis of the average local reference frame of the given 1D geometry

ZAxisValid [in/out]

Boolean

Upon return, contains TRUE if the Z axis of the reference frame is valid, else FALSE

VBScript Example

'Create a cube

set oSelList = GetValue("SelectionList")
set oItem = oSelList(0)
