thats great , so I go ahead with creating profiles , but I did for instance the crescent shape with Extrude ( I selected the section and extruded along the curved path) the result not solid though. for the crescent did you take the vertical curves and then loft? 
thank you

I had no luck trying to extrude or loft a crescent shape created with a polyline so I switched to using a 3DPolyline.  I used the Loft command with the Guides option.

two more points, 1- after subtract is the form still solid, since i did it and the object not solid anymore
2- what if I use the Contour command in rhino to create profiles and then loft them, 
are you using autocad?
thank you

After doing a subtraction the model section you are working with should remain a solid.

I am using AutoCAD 2015 at the moment.  I am not familiar with Rhino.

Make sure you don't end up with any surfaces.

I am doing the 3dpolyline on the crescent form, I have attached the way im tracing it on the form, is this right?
I think I m wrong since in this way is really cumbersome...

thank you

I would not recommend trying to create a crescent by tracing from side to side.  Too much work and it is too easy to click on the wrong geometry.  I did it vertically along one edge.

so you mean tracing vertically and then lofting the crescents together ( what I have is two crescent on both ends but when lofting the form is straight not following the cuvrature) uploads/298250/crescent.zip

You have to use the GUIDES option when lofting the pull the model into its proper shape.  In this case it would be at least one guide at the bottom or the top of the crescent.
