To create a raised panel, or an inset panel, use the new Extrude from a 2D or 3D Surface tool.
Also, you specifically mention offset. You just press the arrow button to the left of the offset distance to reverse the direction of the offset; if you are talking the offset surface tool.
I said "Inset Surface"
What you answered is Insert/Extrude.
Inset is different from Insert
Am attaching a file with the surface. You can open this file in SolidWorks.
Now you can see a surface in the shape of 6 just that it is not planar.
Now how do you create inset surface of this. I know it is easy to create offset of this

Ahah. I know exactly what you mean.
This subject was brought up in 2008:
Then there was a thread started on this forum to discuss the actual functionality, because someone else asked a question about it. I cannot find that thread.
Also, Matt Lombard's blog, http://www.dezignstuff.com/blog featured a discussion that was co-current with the forum discussion. I cannot find that either, and I think it may have been removed from his site. That's too bad, I will see if he can resurrect it, it was a good post.
So, long story short, there is not an easy tool. The earlier thread, if anyone can find it, showed a few methods. One method is to select the edge, and use the ruled surface tool. Then you can use the perpendicular ruled surface option, and make a surface perpendicular to the existing surface. After that, offset the new surface by the distance you want for the inset. You can then use this new offset surface as the reference to trim or split for the "red" area.
This could be better explained with a model and some images, so hopefully someone finds that thread.
