as it stands your question is very vague which makes it impossible to help you. Maybe you can provide some more information about where you have issues. Some questions that might guide you to the information you could give you:
What exactly doesn't work? Which steps do you take?
Are you following a HowTo or tutorial that doesn't work out at some point? If yes, could you post a link to the tutorial and tell us, where it doesn't work?
Can you tell us what you already have tried, what you have read?

What I can tell you is that you should be able to do it from the diagram view when creating a new papyrus project/model and selecting to make a profile.
There you will have a customized palette that should allow you to create your own profile.
However, as pointed out by Benedikt, your question being a bit vague that is the only answer I can provide you at the moment. ^^'
