Can I make objects in a 3D Window clickable in AnyLogic?
the only way you can click 3D objects is by adding some 2D element that is clickable on top of it, perhaps with transparent color, which will allow you to click the 3D object in a 2D animation.
Nevertheless in a 3D window, it's definitely not possible to interact with any object through mouse clicking
Nevertheless if you want to display information by clicking an object in 3D you can instead have a text object to display that information in 3D and you can make that object visible or not when you need.
