Gaieus you were right! I scaled it up 100% per your suggestion and was successful! Thank you for your help!

Hi all! This is my first time here at the forums. I am so glad that there is such a large support group for such ans AWESOME program! I have been using SU for a while and have hit a snag. I have attached two screenshots; one shows a 3d sketch that I made and the other shows the result as I extrude a circle along the path. Can anyone explain why the extrusion messes up around the radii? I have never had this happen before. I have re-modeled it with the same result

Thanks!
