Point
The
Point
tool creates points that can be placed anywhere in the plane, on existing objects, or at the
intersection of any two objects.
If you create a point on an object, it remains on that object throughout any changes made to the
point or to the object. If a point is at the intersection of two objects, the point remains at the
intersection throughout any changes made to the object(s). If you change the objects so that they
no longer intersect, the intersection point disappears, but reappears if the objects intersect again.
Creating a point
