How to show certain edges in render?

Hello,
I want to add black lines to the edges I marked. I did the other outlines with a solidify modifier and a material but this works not for everything. How can I do this ?

I marked them as freestyle edge, but nothing happens

I’m not at home so I can’t show you, but have you enable freestyle render options ? Also from memory it works only with cycles render
