How to model a tunnel section in rhino-grasshopper

“French expression” “Et bien on n’est pas au bout du tunnel”
Meaning that we are still in a difficult situation … I mean the discussion was about using Grasshopper to make a parametric tunnel.

Thanks for the information. There are many strange units everywhere, I was in Artillery and we used Millième (French one (6400 = 1 rev) not Russian (6000 = 1 rev) ). I now more work on astronautics and USA uses for inertia slug.ft², strangest unit I ever saw. For my job I took a XML format of data where you put the unit. So you have not to bother to convert data.

Looks like rest of the conversation has gone off the path of the original topic… Anyways I just wanted to mention that I just happened to serve as an artillery officer also and we also used 6400 per revolution for angle measurement, but it was called mils as in NATO standards. Seems it’s a rounded up value of a milligradian (1/6283).
