And here is a helpful post on how to implement drag and drop of objects in 3D space:

Dragging an Object in 3D Space

Hi, I’m working on a scenario in which I’ll have an object fixed on a particular axis (e.g. x axis). I want the user to be able to click and drag the object along that axis. Obviously if the object was perfectly aligned flat to the screen, I could just use the mouse’s x coordinates to control the x translation of the object. But if the camera is rotated/positioned differently, the object may not be perfectly aligned with the screen. Moving the object along the x axis may be more of a diagonal …

If you search on the forum here you will find more.
