Hello, I'm trying to figure out how I would make a line around a polysurface while conservating its own slope. Lets say I want to construct a slope close to the external walls of a building,so it would be like an helix based on the polysurface. I can adquire the solution using Rhino but only with one turn, i mean, one story. But, when I want lets say three turns and some of the external walls are tilted, things start to become complex.Seems like it is a nice example to develop within grasshopper, but I'm not having success. I've uploaded a rhino file called constantPendant01 to explain better. Thanks in advance for your time,
José
