This is my quick attempt using the Curviloft tool as you suggested. I'm quite satisfied with the outcome. Adding windows and details would be no problem i guess by using lines on surface tool and other projection tools. The problem now is i can't figure how to model the holes, or is it easier to just map it out before rendering?

Oh btw, this is nothing serious, so accuracy is no biggie. Just wanted to try modelling something new.

Guys, what's the most efficient way of modelling something like this?

With all the glasses and various sizes of holes as seen in the image.

Hahah, didn't know the 'Paste in Place' command exist..

Thanks a lot

I'm sorry, but how do i use that script?

How do i add objects into an existing group without exploding the group and grouping back again?
