Create a surface form from a line or geometry edge.
In the conceptual design environment, surfaces are created from open lines or edges, rather than from closed profiles.

- Select a model line, reference line, or geometry edge in the drawing area.
- Click Modify | Lines tab
Form panel
(Create Form). The line or edge will extrude as a surface.
Note: On the ribbon, use the toggle button Surface from closed loops while sketching closed 2D geometry to automatically make surface forms.
