Re: Invisible cylinder
In a mtl file, the number following d matches how transparent is a material from 0 (fully transparent) to 1 (fully opaque).
You can try on a cylinder but don't expect to make round holes in walls with such an object.
If this was your final goal, see this thread for a workaround.
