StrandPosition is an array of arrays: one array of positions for each strand.

Here’s a Python snippet:

from win32com.client import constants
xsi = Application

def dispFix( badDispatch ):
    import win32com.client.dynamic
    # Re-Wraps a bad dispatch into a working one:
    return win32com.client.dynamic.Dispatch(badDispatch)

attr = xsi.Selection(0).ActivePrimitive.Geometry.ICEAttributes( "StrandPosition" )
dataType = attr.DataType
data2D = attr.DataArray2D
for data in data2D:
   for elem in data:
      elem = dispFix(elem)
      xsi.LogMessage( "Vector3: " + str(elem.X) + ":" + str(elem.Y) + ":" + str(elem.Z) )

And here’s a JScript snippet:

a = Selection(0).ActivePrimitive.Geometry.ICEAttributes( "StrandPosition" );
LogMessage( ClassName(a) );

x = a.DataArray2D.toArray();
LogMessage( x.length );
for ( var i = 0; i < x.length; i++ )
{
   y = x[i].toArray();
   LogMessage( "=======================" );
   for ( var j = 0; j < y.length; j++ )
   {
      LogMessage( y[j].X + ", " + y[j].Y + ", " + y[j].Z );
   }
}
