Created a outer profile. How to create center axis passing through form all the profile.

Is each profile a circle?
 
profile is not circle. its uneven profile. Example; the contour of bone at different plane.
 
Circle or not - create a power copy. Fill each "circle" with Fill operation. Then plant a "Point on Surface" with the coordinates 0 - they should land more or less in the center of the circle as the circles appear to be very irregular. Then connect the points. If the spline becomes very twisted you can reduce the number of points.

Thank you very much. It works !!!

Great idea, it will take a bit of time, but it will work 100% sure
 
Alternatively, you can also make a powercopy using a point contructor formula. This approach will give you the exact center of gravity for each (irregular profile).

centerofgravity(`Geometrical Set.1\Sketch.1` )

This is a very elegant approach but I can't understand what does the "centerofgravity()" formula result in? Where do you put that formula? Do I need to pull out the X, Y and Z coordinates from the center of gravity formula accordingly? Can you put more screenshots? Thanks.
 
The idea is that you can define geometries (point, line...) as parameters and assign them a formula. The output of this so called parameter is a geometrical entity (point, center of gravity in your case).

You can see in the box for formula definition the required inputs and outputs.
