Get the position value of the 3D layer in the scene's coordinate system.

hi all...

The scene has an animated camera and a 3D layer attached to the camera.
Is it possible to get the value of the position of a three-dimensional layer
in the scene coordinate system, for a given animation frame.
Of course, there is a menu item "Convert Expression to Keyframes",
but this is if there is an expression, and if it is not ???
