NSided
The NSided primitive is a regular polygon with a given number of sides. The polygon can be made from a Bezier curve or a Polyline. The Bezier type is equivalent to a curve made by the Bezier tool. The Polyline is a connected sequence of line segments. You can adjust the number of sides using the Sides setting, which can range from 3  128.
Note: You can fill the shape using the Curve Fill tool.
