In Context-sensitive Menu

You can add the surface by the the selected lines. The type and shape of the face are determined by the lines you selected to form the face. The result can be a planar face, perforated planar face, cylindrical face, ruled face, or a spline face.

• In order to form a face, you can select lines that form an open or a closed polyline.
• You can select the individual line, which can be the multipoint line such as the spline, or the closed line, like the circle.
• The line can be the guide curve, the line in the 3D sketch, separate line or the edge line of the face.

You can control the shape of the face using guide curves.

• Guide curves can be open or closed and consist of individual lines or polylines.
• Guiding to virtual guide curves will also affect the shape of the edge lines of the face.
• If guide curves are used in the creation of the surface, lofting or sweep is always used as the method. You can add, change or delete elements you have selected for the face when adding the face, or later, by selecting the feature for editing.

If you add a surface to a volume model, the model automatically becomes a surface model.

Add a face as follows:

1. Select the lines as follows.
   • If you select only one closed polyline, the polyline becomes the edge line of a surface.
   • When you select the single closed polyline or the open polyline, you can control the shape of the face by the Guide Curves. The surface(s) are created by sweeping.
   • If you select several than the single open or closed polyline, you can control the shape of the surface by the Control Virtual Guide Curves. The surfaces are created by lofting.

     The guide curve must be tangential.

2. Select the context-sensitive function Faces > Add.
3. Control the face generation with the different options in the dialog box as follows:
   • You can control the shape of the surface using guide curves. Select the lines of the guide curve from the model.
   • View, change or delete selected lines with the buttons. Select a line from the list and click a button.
   • Click the Add button to add a line by clicking it in the model.
   • Click the Flip button to flip the surface. An arrow points in the direction of the outside face. As the default, the outsides of the surfaces are displayed in a part.
   • The selection Closed add to the surface end and first line distance automatically.
   • Click the Apply button to preview the surface to be added when you are adding, deleting or changing the lines of a surface.
