I often have problems with naked edges in my rhino models. I am never quite sure how I got them here and there and it is often hard to repair. I run the check - for naked edges and when the pink areas come up, I try join edge but it appears as though there is only one naked edge and nothing to join it to. I also try to repair it by meshing the model and then doing doing match mesh edges or fill mesh holes but again this has not worked. It is also hard for me to often understand how I got the naked edges because generally the naked edges appear on an area that was built similiarily to another but they only show up in one place. I am wondering if any Rhino users out there could take a look at my model and give me some feedback on what is going on with the pink/naked edges - (1) how they got there (2) how to fix them. If you respond here, I can send the model to you. Thank you for your help in advance!
