## Breakline Tool ##

<div><b>Description</b>: The breakline tool supports users to draw, import and store point cloud breaklines. Based on the excellent display effect of point clouds and terrain models, it can clearly draw water bodies, steep slopes, rivers, roads and other breakline elements with high contrast. On the basis of drawing breaklines, using the drawn breaklines to assist [Tin Tool](TINTools.md) in adding breaklines for terrain editing and point cloud classification processing.

After enabling memory point cloud editing, you can activate the edit tool for breaklines and correspondingly generate a broken line object loaded into the directory tree and participate in various windows for editing.

The broken line editing tool includes sub-function modules such as broken line importation, broken line drawing, utility tools, broken line selection, entity capture and layer management.</div>

### Draw Vectors ###
Supports drawing of multi-segment lines or polygons as breakpoints. For specific operations please refer to [Vector Editor Entity Vectorization](../VectorEditor/EntityVectorization.md) for multi-segment lines or polygon drawings.
	

### Utility Tools ###
Supports deletion of breakpoints and attribute queries. For specific operations please refer to [Vector Editor Basic Functions](../VectorEditor/BasicFunction.md).


### Snap ###
Supports capturing existing breakpoints or points clouds during breakpoint drawing process. For specific operations please refer to [Vector Editor Entity Snapper](../VectorEditor/EntitySnapper.md).


### Layer Management ###
Allows addition of layers or modification of layer attributes. For specific operations please refer to [Vector Editor Layer Management](../VectorEditor/LayerManagement.md).


### Storage ###
When exiting the classification editing function, users will be prompted whether to save the modified breakpoint file. Click "Yes" to store and "No" to cancel storage.

Users can also use the layer management tool for breakline storage.
