## Geometry1D.StartSubComponent0D

### Description

Returns the index of the start 0D SubComponent of a given 1D geometry as an Integer.

### Parameters

Parameter | Type | Description
--- | --- | ---
compIdx | Integer | Index of the component
Possible Values: | Description:
0 <= compIdx < Number of 1D geometry | The compIdx must be valid

### Examples

#### VBScript Example

    'Create a cube
    CreatePrim "Cube", "MeshSurface"
    set oSelList = GetValue("SelectionList")
    set oItem = oSelList(0)
    set oGeometry = oItem.obj
    oNb1D = oGeometry.Nb1D
    set o1DGeometry = oGeometry.Geometry1D
    ' Loop on all the 1D geometry
    for i = 0 to oNb1D - 1
    oStart0DIdx = o1DGeometry.StartSubComponent0D( i )
    oEnd0DIdx = o1DGeometry.EndSubComponent0D( i )
    LogMessage "Component [" & i & "] 0D start SubComponent : " & oStart0DIdx
    LogMessage "Component [" & i & "] 0D end SubComponent   : " & oEnd0DIdx
    next
