Making my own prefabs

[Damocles]

How can i make my own prefabs, such as a heater or something like that? I don't want to use Brushes.

 

You don't actually have to tell me how to make them, just tell me where to get a piece of software to do it with. I can find tutorials all by myself

You mean, How do I make Models?
