I used the flow command to make a solid ring but I think it is overlapping (I did check the lenght of my target curve and base curve, they were the same). What do you people would recommend to fix this? I did delete the surfaces in between but that was useless because the ‘‘outside’’ surfaces and curves are still overlapping. I am fairly new to Rhino and I don’t know many command. Is there an easy or fast way to fix this?
