Making a wall-mounted shelf

…In place families are great for other kinds of work too.…We have created a custom door within this wall.…You might want to also add something to the wall like custom case work.…Imagine putting a shelf or something of that nature on…the wall that can be used for decoration or whatever.…So we're going to go ahead and create a shelf here.…And…I want you to kind of zoom in on level one…and there's two more reference planes here that are in play.…

Neither one of them, if you note, have any kind of name to them yet.…So we're going to pick up the first one…here, and we're going to call this shelf right.…And then we're going to take this next one and call that shelf left.…I try to keep the names usually kind of simple, and…I do try to make it as many times as possible.…What's the difference between left and right, and also up and down.…So, what you might want to kind of keep that also in play, as well.…

So now we have these reference planes figured in, the only thing that we need…to do is check out to see what height our shelf is going to be.…
