SIAddPointOnCurve

SIAddPointOnCurve( InputObj, [InsertPosition], [X], [Y], [Z], [Local], [CurveType] );

Parameters

Parameter Type Description

InputObj String Curve to set points on.

InsertPosition Double Where to insert the point or knot.
Default Value: 0

Possible Values:

Description:

Indexofanexistingpointonthecurve. The new point is added after this point. Points are indexed starting at 0.

Percentage The new knot is inserted at this percentage along the curve length, at the specified coordinates.

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
