Jim,
Congratulations on another successful project. I am impressed at how far and wide your interests and influence ranges.
I believe your anecdote about the computer screwing up the drawings will be valuable to many of us. It is only by taking full responsibility for our work will be able to continue to improve.
It is the best of all possible lessons for people to move through the process of first blaming the software, double and triple-checking the human work, and discovering where the errors actually are (most often in implementation).
This is a stronger lesson than would be learned by not treating the software with suspicion in the first place. When I complain to my tech guy about the computer, he invaribly replies with 'PEBCAK'
Problem
Exists
Between
Chair
And
Keyboard
In almost every case he has proven to be correct.
Kindest regards to all.
Joel
