Description

Adds a point at the start of a curve.

Scripting Syntax

SIAddPointOnCurveAtStart( InputObj, [X], [Y], [Z], [Local], [CurveType], [PreserveTrace] );

Parameters

Parameter Type Description
InputObj String Curve to set points on.
X Double X coordinate

Default Value: 0

Y Double Y coordinate

Default Value: 0

Z Double Z coordinate

Default Value: 0

Local Boolean True if points are in local coordinates, False if they are in global coordinates.

Default Value: False

CurveType Integer Type of curve

Default Value: -1

PreserveTrace Boolean True if the current trace of the curve should remain intact with the addition of the new point.

Default Value: False

Examples

VBScript Example

'This example shows how to add points before the start of a curve
newscene
'Create a curve and add points at start.  
'Adding points at start will create a curve that
'has the same trace as adding the same points at end
'but with start and end points reversed.
