Blue Box But no Model, Plus Animation

Why when I import a model does it just show as an empty blue box but no model, also can someone please tell me how to import an animated model without losing its animation. Thanks

What model are you importing that comes in with only a blue box? What animated models are you talking about?

Dave, there are many models that I have tried to import that have just come up as a blue box. I would say that most of them are probably glb files that I am trying to clean up and rescale. And every animated file I import loses its animation. These problems are not specific to one model. It very well might be something that I am doing wrong, for I am a complete newbie at using 3d software. Thank you so much for responding.
