Michael,
It appears to me that the "O" is made up of one segment. If I select the face it is all selected with one click. Same goes for the outside curve and the inside curve. Attached is the file that I was working from. I believe it to be the original file, rather than my unsuccessful attempts to break the O and recombine it.

Also thanks for the tip on the rebuild. I think that will help with some of the problems that I was running into while trying to chamfer after trimming out an area (along with the text).

I don't want it to sound like I am struggling with your program, for the most part I find MoI very intuitive and a real pleasure to use and learn.

Thanks for you help,
John
