That’s exactly how you do it, it’s just that sometimes things don’t line up. It’s trickier that it seems. You scale to zero, but things don’t always follow the normal you want. But also when it works, it can cause a mess and pinching.
You know, there’s so ugly poles there that will give you problems. I’m not sure if that’s your topology you’re going to go with, but that middle one seems to have 8 edges connected to it. A pole has maximum 5, when you go up to 6 that is bad news. Also the one at the top that is open, if you extend it upwards, it’ll become a six sided pole.
