I'm a small time structural steel fabricator and am having problems bidding jobs because of the fact of producing shop drawings at the end. I don't understand why architects need them if you are doing exactly what they propose. I am capable of making them, but have not found a better way then the time consuming pencil and grid paper. Are there any inexpensive, simple programs for the computer that you have had success with? I am not very diligent with computers but know the basics. If anyone has advice i appreciate it.
