If I can place an item it's color is green. If I can't it's color is yellow.
This is not good enough for me. I think It's better to see placeable area like yellow line around my character.
Is there a mod or command for that?

I don't know, but there are mods that extend the area where you can place items. They are called "Long Reach", and I couldn't play anymore without one of them.

It's useful thx.

you can use stone or concrete, use the + and - buttons on the numbpad to increase the brush size and you will see the green circular reach area.
