I haven't been posting lately because I've been just getting on with making this thing. But I took the time to save screen shots as I worked so I can show you some of the stages. This is the indicator lever (I guess).





Then there's this thing which looks like an air conditioner or venting system on the ceiling of the cabin. This might look like the beginnings of a Boolean operation but the little cylinder is just there as a reference object that I use while I use the interactive split tool to make a hole there. I love that tool.
