Since the autoshape tool creates standard shapes, rectangle etc., those shapes are edited by their type. However the Autoshape tool also creates three additional types: Polyline, Curve, Star (5 pointed).
Autoshapes (line, polyline, curve, ellipse, circle, rectangle, parallelogram, trapezoid, star, autocloud, right-angled, equilateral and isosceles triangles)
Ellipse
If ellipse' radiuses are nearly equal, then it is drawn a circle
LineCircle
A circle is drawn If the shape approximates a circle and the radiii are nearly equal.
Ellipse
A circle is drawn If the shape approximates a circle and the radiii are not equal.
Line
A line is drawn If the shape approximates a line.
Polyline
If end points are located nearbynear to each other, the polyline is will be closed.
If the angle between the nearest two consecutive line segments can be approximated to are approximately 90 degrees, a right angle is made. The angles are approximated, when polygon points are moved.
Closed created.
A closed polyline with 3 points - will result in a triangle - can It can be a right-angledtriangle, equilateral and or isosceles.
Closed polyline with 4 points can be recognized as rectangle, square, parallelogram, trapezoid.
If end point of parallel side in a quadrangle is moved along parallel lines, the property of parallelism is being kept.
Right angles in quadrangle are adjusted as well.
Another form of polyline - star. At the input regular star is automatically generated, later it can be made irregular. Star can be edited by moving end points or inner/outer radius points.
Curved line is approximated by spline, it can be closed and unclosed
Autocloud is created when closed curved line can be approximated with a cloud markup
