Description
With break command you can divide one object into two objects, or you can remove one part of it(this part will be defined by two points that you have to pick).
First you have to select the object.Then you have to define the first break point and the second break point.When you pick this points , the part which is defined by the two points will be deleted from the object.
Remarks
The two points can be the same point. In this case you only explode the object into two other objects(for example you can cut a line into two lines).
If break command runs over a circle , you have to set two different points in order to see a result because a circle cannot break in one point. After break command the circle becomes arcs.
