Ruled

$image\icon171.gif$

This command creates a surface using two or more curves, each of which define a cross section of the constructed surface at a specific location. The surface is created by connecting the corresponding points in each curve with a Line link type. The curves will be connected in the order they are selected. If the selected curves do not have the same number of points, the system will insert points where necessary to create an equal number of points in each curve see Automatic Reparameterization.
