## Classify by Interactive Editing ##

### Summary ###

Because it is difficult to attain 100% accuracy with the automatic classification algorithm, human-computer interaction classification is usually required to meet product requirements. Manual inspections and reclassifications are performed in the profile window. The profile tool is used to examine the classification results and modify them. For the accuracy improvement of the classification, real-time changing TINs can be generated to assist the classification.

### Steps ###

1. When performing interactive editing and classification of point cloud, it is better to ensure that the point cloud is displayed in the class display mode.Click on the color bar toolbar <img src="../../Icon/DisplayBy/displayclassfication.svg" height="20" style="vertical-align:middle"></img> to display by class.
2. Click <img src="../../Icon/Profile/Profile.svg" height="20" style="vertical-align:middle"></img>, open the profile window to start checking the classification results. In the main window of profile mode, point cloud can only be displayed in 2D mode.
3. Select the point cloud in the main window and select the corresponding point cloud in the profile window. Please refer to [Profile Editing](../ProfileEditing/DrawProfile.md)。

4. For points with inaccurate classification, you can use the [Select Tools](../ProfileEditing/SelectToos.md)to classify again. Set the classes through[Classify Panel](ToolReference/ProfileEditing/ClassifyPanel.md), classify the pionts selected by selection tools to the target classes.

5.In general, to visualize point cloud classes more intuitively, you need to generate a TIN. Please refer to the [TIN Tools](../ProfileEditing/TINTools.md)。

6.If the manual classification error needs to be modified, you can undo the previous operations with the shortcut **Ctrl + Z**, or clear all temporary operations by clicking <img src="../../Icon/Common/Undo.svg" height="20" style="vertical-align:middle"></img>.

7.After confirming the classification results, you should click<img src="../../Icon/Common/saveEdit.svg" height="20" style="vertical-align:middle"></img>to finish save.

>Note: After classifying by editing, you need to click the **Save** button to save it in the file.
