• Intersection: line¹ - line¹

  A point of intersection appears. As soon as both lines¹ become parallel it vanishes. The point of intersection does not exist on the board anymore, but still exists internally - it is not deleted. All objects depending on the point are hidden as well. In the list "Objects" in the dialogue  object properties these objects are displayed gray. Segments and rays are treated as lines.

• Intersection: line¹ - circle

  In this case both points of intersection are created. If the line¹ and the circle do not intersect anymore, all points of intersection and objects depending on them are hidden.

• Schnitt: Circle - circle

  As before two points of intersection are created, which as the case may be are hidden.

The intersection of two objects can also be created directly. A mouse click on the place where both objects intersect while being in  Point-mode is enough. If one of the objects is a circle the other point of intersection is created as well.
