Hello, I need to make something in RDS5.5 as its been to long since I made anything. Well cycling is another hobby, I just got a great bike, and now I want to model my bike in RDS. I can't think of a way to make the chainring, can you think of a way. Thanks, Kevin For a pic of the bike I have copy-paste this http://www.caninet.com/~bicycle/image311.jpg
