move model from asset folder to hierarchy or scene with c#

Hello, I use recently Unity. I need help. Through a script I copied a file (a model .3DS) in runtime from a folder on my computer in the Assets folder. Now I should insert the model in the scene and in the panel hierarchy. I know that just do a drag and drop if you are not in runtime, but I need to move in runtime, instantiate the model in the scene through scrip c #. Thanks for your help.

 

You can do this using the resources function found here

Do the note of ALL the documentation, this code will not work unless implemented correctly.
