Would it be technically possible to use the first two vertexes, as defined by the users, to then automaticaly create a final arc using the first vertex as the center and then the second vertex to calculate an arc to close the polygon? The second point would be used as the initial xy AND the final xy, we would then calcualte the opposing side of the circle as the third and intermediate vertex to close the arc. We may have a line from the vertex to one side but I don't really care about that......
Thanks in advance for your opinion,
Steve
