grabcad

Good morning colleaguesI share with you a project that I was doing in grasshopper, it really is a nice experience, I have been able to recognize a large number of commands, the design is about a spiraling observation tower, I made a mistake again at the end of the spiral, but well, that's how it goes more or less , the important thing is to be able to recognize the commands to make the extrusions and the pipe profiles, as I will do something more complicated.a hug for everyone.
