Function Description

The break function is used to break a line object into a new object.

• The break function is used to break the line object anywhere the mouse clicks.
• A layer that is suitable for breaking can be an object of a line layer or a line object of a CAD layer. The Layer of Object to be broken is also required to be editable.
• When breaking, you can turn on the snap function to quickly and accurately locate the point you want to break. For example, when breaking the intersection of line objects, you can turn on the snap function.
• If the selected break point is the intersection of multiple objects, the Select the object that you want to break dialog pops up to support the selection of objects for Join to Break, and Select Objects in the list is highlighted in the map.
• Description of the enclosed object break.

  In SuperMap, a closed line object is considered to be an object whose start and end points coincide. And the starting point and the end point of this coincidence are called endpoints.

  For closed line objects, such as circles, rectangles, and so on, after a single break operation, the system automatically breaks the ends of the closed object at the same time, resulting in two line objects.

• After the break operation, the two newly generated line objects are temporarily displayed in different colors to distinguish them.

Function entrance

• Object Operation tab-> Object Editing group drop-down box-> Break.

Operating instructions

1. On the Object Operation tab, in the Gallery controls in the Object Editing group, click the Break button to perform a break operation.
2. Map mouse prompt: Click to break. You can break an object by clicking on the location where you want to break it. The two newly generated line objects are temporarily displayed in different colors (red and blue) to distinguish them.

   After the operation is completed, the original line object is deleted, and a number of new line objects (number of breaks + 1) are generated. Their System Field: attribute is assigned by the system, and the Non-System Field: attribute of the original line object is retained.

3. When executing the Break Object Operation, if the selected break point is the intersection point of multiple objects, it is supported to set the object of Join to Break. In the Select the object that you want to break dialog box, you can check the object to break in the list. The selected object is displayed in the Highlight in Map.
