Extrude Between Two Paths effect.extrude Lines Polygons Follow curves true This effect draws lines between each nth node of each selected path. It therefore works best if all selected paths have the same number of nodes. There are 3 main options: - lines: segments are created between the corresponding nodes. It is possible to select the option "Combine lines to single path" so that the segments that are created are subpaths of a single path; otherwise, the segments that are created are separate paths grouped together. - polygons: Polygons with straight lines are created between corresponding pairs of nodes of each path. The polygons are grouped together. - follow curves: the same as polygons, but the 'segments' of the path that lie on top of the original paths will follow the same curves as on the original path. The lines will be inserted above the bottom of the two elements. path
