To use the Connector tool select the curve that describes the outline of a major connector. For major connectors with holes in them, select the outside curve first, then the inside curve.
Stipple Pattern  A drop-down list of stipple patterns to be applied to the surface of the major connector.
Stipple Scale  The horizontal scale for the stipple pattern. A larger value will expand the pattern to cover a larger area.
Stipple Thickness  The vertical thickness of the stipple, on top of the base thickness value.
Base Thickness  The distance from the refractory model (plus any relief wax) to the bottom of the stipple.
Linear Falloff  The falloff angle to be applied at the edges of the connector. A larger value will yield a smoother transition and a slightly wider major connector.
Use Defaults  Returns the previous changes to their default values.
Apply  Applies the parameters to the selected curve to create a major connector.
