Bruce,
"yep it's fun checking over the drawings and telling the draftsman/ architecs there stuff wont work in the field"
In all my years of being a union Glazier, that is something I always enjoyed. I've had plenty of engineers tell me "well that's how I drew it, so that's how I want it built..."
They live on a piece of paper that they draw....actually building something in the "real world" can be completely different. I banged heads with an engineer on the Trump towers so bad, I thought he was going to get fired lol.
