Editor
Control the initiation and termination of contour line editing. Contour lines are essentially vector objects; during editing, the system will not recognize whether entities in the file are contour lines, but operations will only produce the expected results when applied to contour line entities. This module supports editing only one contour vector object at a time and includes functions for selecting files for editing, creating new files, importing files, saving, and ending editing.
Start Editor
Click Edit -> Start Editor
If there are vector object data in the editing window, a dialog box will appear to select the vector object data. The vector object data already loaded into the editing window will appear in the selection list. Choose the data to be edited.
If there are no vector object data in the editing window, a dialog box will appear to select vector object data from disk for editing.
Once editing is initiated, other functions on the vector editing toolbar will be activated.
During editing, the vector data being edited cannot be removed from the editing window.
New File Editor
Click Edit -> Create New File for Editing
- A file selection dialog will appear. Generate the corresponding vector data file based on the user-selected path and load it into the editing window to begin editing that vector data.
Once editing is initiated, other functions on the contour line editing toolbar will be activated.
During editing, the vector data being edited cannot be removed from the editing window.
Import File
Once editing is started, you can click Edit -> Import File
- A file selection dialog will appear. Load the user-selected vector data file into the currently edited vector object.
Save
Once editing is started, you can click Edit -> Save to save the current edited data to the original file.
End Edit
Click Edit -> End Editing or click the End button 
- Ending the editing session will prompt a dialog to save the editing results. Choose as needed and exit the contour line editing module.
If editing is not started, you can also directly click the End button
