I have only started learning rhino and this semester at school we needed to make a 3d model of a building and i got a museum in Lyonn which is a pretty complicated one, especially for a beginner. I got a problem that it shows me a lot of naked edges in weird places that i cant really fix by JoinEdge. I tried changing tolerance but i think it made things even worse. I had fixed almost all of the naked edged and then it again started showing me all of the naked edges i had fixed a minute ago and i think it added some new ones. What’s the problem?
