The Covering function in the Advanced Surfaces menu creates G1 quality n-sided patch surfaces from a set of closed trimmed boundary curves or edges. Options allow tangency conditions to be held at boundaries or not and additional guide curves and point to be used to control the shape. This function is especially useful for quick reconstruction of bad surfaces.
