The user can create a surface geometry by the following procedure.
• Point, Direction, Point, Angle, Distance
• Point: Selects a point to define the arc center.
• Direction: Defines an axis direction for generating the arc.
• Point: Selects a point to define the starting point of the arc. It is the information of the arc radius.
• Angle: Defines an angle of the arc.
• Distance: Defines a distance of the extruding length.
