Closed Spline

Add a closed spline. When adding a line, you can use an auxiliary function to mirror a line being drawn automatically. You can use ruler functions, when clicking points of a line.

Click curve points, minimum 4 points and maximum 20 points. Accept selected curve points by selecting Confirm, and the line is drawn from the last clicked point to the start point of a curve.
