The Point Trace Polygon tool allows you to trace out a polygon using Points laid out on the canvas. First layout the corners of some shape with the Point tool, and then simply trace the shape with your finger. You can easily remove the points after construction by using the Delete Path Collection tool. The only construction options available are the number of Bezier Points and whether or not the first vertex and last vertex are connected. The Bezier points and the vertices of the polygon can be manipulated just as in other polygons by using the Move Bezier Point tools and the Move Vertex tools. See also the Mark Point Polygon. Here’s an example of Point Trace Polygon construction:
Note that Snapping is required for use of this tool.
