Mouse Position on gui to Vector3 Position

Is this similar to what you’re doing?

Convert 3d position to 2d relative position

[Screenshot_2] As you can see from the image, the 2D plane is the black part, and the 3D position is the client’s mouse hit position. Subtracting the position from the top left corner highlighted in red from the mouse hit position works fine but does not work for objects that are not at a perfect 90-degree angle.
