1. Point-to-Point Measuring:Allows users to measure distances between any two points in the scene.
   Utilizes raycasting to detect points clicked by the user.
   Calculates distances using vector math based on the positions of the selected points.
   
2. Multi-Point Measuring:Extends the functionality of point-to-point measuring to handle measurements involving multiple points.
   Provides a user-friendly interface for selecting and measuring distances between multiple points.
   
3. Area Measure:Enables users to measure the area of irregular shapes or enclosed regions in the scene.
   Utilizes the shoelace formula to calculate the area based on the coordinates of the selected points.
   
4. Coordinate Flags:Allows users to place flags or markers at specific coordinates in the scene.
   
5. Selected Item Info:Displays detailed information about any selected object in the scene.
   Retrieves and presents data such as position, rotation, scale, and other relevant details of the selected object.
   

These tools are implemented using Unity's Editor scripting API, including GUI handling, event detection, raycasting, and mathematical calculations to provide a seamless editing experience within the Unity Editor environment.
