Defining Windscreen Elements on a Curved Work Surface

Define curved parameterised windscreen antenna elements on a specified work surface by using surface lines, surface Bézier curves or an array of linearly spaced lines.

1. Create a line in the curved work space.
   1. On the Windscreen tab, in the Create Surface Curve group, click the  Surface Line icon.

   2. Specify the Start point, End point and Work surface.
   3. Click Create to create the surface line and to close the dialog.
2. Create a surface Bézier curve in the curved workspace.
   1. On the Windscreen tab, in the Create Surface Curve group, click the  Surface Bézier Curve icon.
