Even if he didn't know what reversing the vertex order does to a mesh .... by doing what I said, i.e. select the face in question and reverse the order >> he does now !!
There was no reason to explain in detail the function of this tool + what it does and why... because by doing what I told him to do explains it just fine.
It solved his prob with the faces, facing the wrong way + showed him what tool to use to prevent this from happening again... he now knows that if he has some BLACK faces, then thats how to sort them.
OK, I could have explained that to prevent them from happening in the first place he should only make his faces in an anti-clockwise direction ( assuming he's vertex editing ) or I could have told him to make sure he is extruding in the correct direction.... But thats not what he was asking.
He had a prob - I told him how to fix it - he fixed it ... whats the big deal with how I explained it to him ?
EDIT:
As for him asking in the correct way .... well, I just read between the lines and could see what he was asking.
