Hello, I've been trying to figure this out for a day now but can't figure it out. Im trying to add an internal thread through the side of a cylinder, I used the helix/spiral and swept boss to make the thread, but when I sweep the helix it cuts some of the sides off of the cylinder and cannot figure out how to solve this problem of making the thread while still maintaining the edge of the circle. I hope this makes sense I have posted a picture of my problem below. Thank you very much for your help and responses.
