Hello false1

There are so many ways to achieve what you want to I remember a way that was for making buttons which if I am misreading your original post might also work the tutorial is for modeling a chair with buttons but about starting at 3 minutes into the tutorial he talks about a tool that you can use to make a circle from square I might be misquoting but here it is https://www.youtube.com/watch?v=8gVOOxyMbnM&index=27&list=PLHr34e1LpWogv8q3Ng2ObrxCvUD-k6wv3 The creators of this video CG Masters have an excellent site and some of the best tutorials in my personal opinion and they do have some tutorial DVDs a bit pricey but I got one of the sets that I am still working thru and I must say I am amazed at how well they are done

Hope it helps
