If you are asking about uploading your console Sims to your sims3.com/mypage ?
This is not possible due there's no connection between the console version and the website.
You're best bet may be to try to recreate your console Sims/houses via the computer version and then upload them through the launcher to the website.
To note, for those who wonder: While it's similar to the Sims 3 game on the pc, the console version's save files are incompatible with the pc version. This means that Sims/houses created on the console cannot be shared with the pc version.
