Hello chrisd,

Apparently you misunderstood my first statement which made my following statement unclear, I'm talking about calculating the optimal tool path from each point on each line of each triangle in relation to its neighbors. I'm not sure how you could say that my computationally impractical statement was not true. I didn't say it was impossible, but it is highly inefficient, and unnecessary given the other options that are available. Did the CNC mill each one of those million plus triangles poly by poly fifteen years ago? Of course not, tool paths were created from an input surface. But I guess that's the point, start with a lightweight surface set and add detail where needed through further secondary finishing processes that are appropriate for the desired output.
