MY IMPORT 3DS MODEL IS NOT PASTING

I TRIED IMPORTING A 3DS MODEL FROM IMPORT 3DS MODEL AND WHENEVER IT IS SELECTED TO PAST IN CARVECO, THERE IS NO MODEL.

THE MODELS WERE TAKEN FROM THE INTERNET AND SAVED TO DOCUMENTS.

JUST WANT TO KNOW IF I AM DOING SOMETHING WRONG.

I HAVE SENT A VIDEO TO SSHOW YOU.
