An OpenSCAD module to render a 2D polygon outline including rounded corners.
It takes a list of vertices as [X,Y] points (vec2), a boolean value for whether to fill the polygon, and a float of the thickness of the outline. The outline is centred on the line between vertices; rounded corners are centred on their vec2 point.
It is not possible to make the script generate polygons inside of the given vertices as it would require calculating a hull, which is not possible in OpenSCAD. You will need to change the positions of vertices to suit.
It supports both filled and unfilled polygons.
Example Usage
use <OutlinePolygon.scad>Points = [ [0,0], [0,1], [1,1], [1,0] ];
linear_extrude(5) {
OutlinePolygon(lineThickness=4, fill=false, points=Points, $fn=24);
}
