When using the ByFunction technique, properties such as LevelName, Transparency, LineStyleName, or Color can be set in the same was as modelBased nodes created using other techniques.

They are listed, by alphabetically by default, along with Function and FunctionArguments. Here the Color property is set.

                                    {
                                    Line ln = new Line(); 
                                    ln.ByPoints(startPoint, endPoint);

        Color                     = 3;
    }
}

Properties can be set directly within the function of the ByFunction technique. This function demonstrates how to directly assign a property to the top-level node.

        FunctionArguments         = {point01, point02};

When creating an array of nodes, the color can be a single one or a matching array.
