# path_scaling_sections
Given an edge path with the first point at the outline of a shape. This function uses the path to calculate scaling factors and returns all scaled sections. Combined with the `polysections` module, you can create an extrusion with the path as an edge.
Given an edge path with the first point at the outline of a shape. This function uses the path to calculate scaling factors and returns all scaled sections in the reversed order of the edge path. Combined with the `polysections` module, you can create an extrusion with the path as an edge.
In order to control scaling factors easily, I suggest using `[x, 0, 0]` as the first point and keeping y = 0 while building the edge path.
You can use any point as the first point of the edge path. Just remember that your edge path radiates from the origin.
