If you have only the points of a path, using `polyline3d` or `hull_polyline3d` is a simple solution. If you know the cross sections along a path, you can use `polysections` to do more. When using this module, you should use points to represent each cross section. The points of your cross section should have count-clockwise indexes. For example: ![polysections](images/lib-polysections-10.JPG) -If your 2D shape is hollow, set the `triangles` parameter to `"HOLLOW"` and index the points as the following: +If your cross section is hollow, set the `triangles` parameter to `"HOLLOW"` and index the points as the following: ![polysections](images/lib-polysections-5.JPG)
