Hello, I'm trying to apply a surface to this railway tunnel I've created. I've tried to used Loft without success and I'm not even sure it's the proper command to do it. I'm basically trying to put a surface on the side of the tunnel like I've already put in the front (with the HATCH command).
I'm using AutoCad2014. Can someone help me guiding through the process? Thanks for whoever helps me, it's really important to me!
