The Ruled panel allows you to create surfaces and/or meshes of plate elements from nodes, lines, and/or line segments, in any combination. Nodes in the mesh being created are placed on a surface created on a linear basis between the two sets of selected entities. The Skin panel allows you to create a skin surface and/or mesh from a set of lines. Note: The Skin panel is for lines that are stacked next to each other. If lines form a closed loop, use the Spline panel. 我理解为，前者必须设置两组，后者随便，但后者的线必须不是封闭的，封闭的用spline
