First of all, sorry for these lame questions of mine, I never really did map with patches or LOD terrain...
I've got a little piece of terrain, and I'd like to turn this into a trench (this picture is with terran shading turned on so that you can see it's not flat):

But if I select individual patches, they're a bit too big...

And as an effect I get this (pretty sh*tty, huh?

I thought of making an overlapping patch, but I'm sure there's a better and simpler way... Am I right?
And yeah, I know the grass and road textures don't match, but I don't care at the moment.
