View cross section

Hello,

I am working with the wing model shown in the picture. Here it is represented its view in the xy plane. As you can see, in the bottom of the structure there are some lines which have an inclination and I need to view the cross section of these parts. The problem that I have is that the 'hidden line' command just let me do the views in the standard planes (xy , yz and xz). Anyone knows a possible solution so I am able to do the cross section with inclination?

Another question  related is if you can obtain the properties of the cross section with some command.

Thank you in advance
