@Trainman2001 Beautiful work - I have that building for a place on my next layout. Seems to me many O town/city buildings don't have good proportions relative to the prototype. That one looks pretty narrow front to back. But if it had more depth where would it fit on a normal layout?
Are you making battleship guns? I missed your earlier post so I know the answer, but did you remove some of you images or are the powers concerned someone will print your turret for nefarious purposes.
One of these days I have to learn 3D printing. Started to learn autocad, but never had a consistent use for it so I kept forgetting commands.
