Nem todo arquivo possui formato texto, utilizando somente caracteres imprimíveis.

Um arquivo com extensão .3d sugere um arquivo binário, contendo um modelo 3D para software de modelagem. Podem existir diversos softwares que utilizam arquivos com esta extensão.

Você precisará identificar a qual programa o arquivo pertence e, depois, descobrir se existe alguma documentação sobre o formato, mas certamente não poderá abri-lo no notepad.
