Indeed, the image shows it all, but the problem is that I want the windows to have a specific shape, namely a box with a rounded top and bottom. Next to that, the Challenger's primary hull is complicated, as it is done completely by hand instead of using tools. Time consuming, but it does mean that when you compare the side and front view, and when drawing a line from the top where the bridge is to the side and the front, they have different lengths: the line that goes to the front is longer than the line that goes to the side, and that was something I couldn't get done with a tool. Back then, anyway
I
could redo the primary hull, but I've put so much time in it that I'd rather not do that...
But anyway, in the following screenshots I left the View -> Rendering -> Edges on, so you can see how complicated the primary hull is. Next to that, I copy pasted my windows, put them on my bridge module and rotated them so that they are now correspnding to the edges on which I pasted them. Clawhammer showed me a variation of the Follow Me tool as it is present in MAX, and with that one, instead of creating a tube or so, that Follow Me tool copies the shape you make and spreads the copies out over the selected line. I find that very hande, so I'm going to see if there's a way I can do that too. I'm afraid it's not possible, tho...
