I AM NEW TO PRO/E,,,PLZ HELP ME IN CREATING BELOW CAD FILE ONLY THE FAN PART .....AND STEP BY STEP PROCEDURE HOW TO CREATE CAD FILE IN PRO/E.

 

I won't be writting step by step instructions to model that part for multiple reasons. 1) That isn't the purpose of a forum to do your work for you... 2) can hardly tell full shape features from the image. 3) No dimensions

What I will tell you is you will have to use a Swept Blend in Creo to obtain that shape feature. The trajectory line will be an arc and then you must sketch individual sections to obtain the cross profile. If you have more detailed questions we would be happy to answer them.

 

I agree with everything CPPM said but I would add that another option for creating geometry like this in Pro is to surface it.
