Understood - I read those exceptions and his attempt to use them. Obviously neither exception applies; but it's the fact that the definition of engineering in ORS 672.005(b)[0] is so broad is worrying. Saying that I can do some math and create a nice graph for my neighbor, but not post it on imgur without a fine, is a step too far for my taste.
Please do yourself a favor and read this for a while instead. Taking bits of statute in isolation and extrapolating from them is a Bad Idea, and if ou ever get sued it will impair your ability to understand your own case. I've seen what that looks like close-up and it's not pretty.
