Design vs. engineering question

[Alaskan Son]

Gerry,

Thanks for you tactful response.

I'm not sure anyone is really understanding what I'm asking though. Its not a question of to engineer or not to engineer, not even a question of whether or not I'm qualified to do the calcs myself.

The question is...When performing professional design services (especially with Chief which is not an engineering program), where do you think a designers plan drawing responsibilities should end, and the engineers plan drawing responsibilities begin?
