When you're starting a floor plan with Revit, you don't necessarily have to worry too much about exact lengths or locations because there are other tools that you can use to help you put walls into exact locations, and to exact lengths. A couple of tools that we're going to look at next is the Offset tool, within walls, and another one where you can divide a space up without actually doing the math to know what each side of the space should be. So let's take a look at how some of these tools can work for you. Let's go to Project browser and go to floor plans and pick first floor.
I want you to zoom in on the area where you've got the stairwell. So you can see, basically, these four columns pretty well. Next, let's go to the Architecture tab and go to Wall. And you'll notice some properties that we have an interior 4.5 inch partition, which we've been using. The only change we're going to make here is to take this top offset and change that. We're going to change that to zero and six. So we now have a wall that'll go up to the first floor.
And then exceed that by six inches. Next thing we're going to do is we're going to come in and pick up the location line, and we're going to make this finished face interior. The reason that we're going to do that is that we're going to take and draw a wall offset from this grid line, and we're going to kind of make it into a hallway type wall. So we're going to make sure that our finish face is set there, and we're going to have chain on as well, and our offset from the grid line's going to be five feet. So I'll just go ahead and type in a five there, and then I want you to come down to the first column on the grid line, and pick it and then draw all the way across.
You come up to the next one, click there, and then come down. Now you'll notice that offset is still on. And I have chain on, so what I need to do is clear the offset. So I'll come in here and I'll make sure that's zero. And then I will come down straight to the next grid line down here and click. And you'll notice that it gives me a nice clean corner there, and I'm on the end with the other grid line. I'm going to come up here and click modify.
Now we're not done with the offset command because let's say that from this wall, I need another wall over here ten feet. So, going back to the wall command and picking that. Picking the same partition. Notice everything is the same. All we need to do is come in here and pick our offset to be ten feet. Now, over the on Draw panel you have a number of tools. So far we've just been drawing lines. We're going to actually use another one that's fairly useful which is called pick lines.
So go ahead and click on that, and what we're going to do is we're going to come down here, you can zoom in a little bit, and I want you to pick the interior face of this wall. And click. And you'll see here that you have another wall in place. Go ahead and click Modify. Now, here's the trick Is this actually ten feet in between on the interior? Well, let's take a look. We're going to click on here and you'll notice that it says currently ten feet four and a half.
Take the witness line that's here and click on it because it's a toggle, until it shows up into the middle. Or center and then you'll see it come to the inside face. Same thing happens here, and you'll see here that it's actually ten feet. There's a little icon here for a permanent dimension. Click on that. So now you have a permanent dimension shown, and that the interior for this wall is ten feet. Now, let's imagine as well that you want to take this area up here and you want to divide it into three equal spaces.
So, what lets do this. Let's take the wall. We're going to start off by defining the wall off of this grid line here. So, I'm going to use the center wall line. As we're going to use that as our center, and then just come down. And hit Modify. And so we want three offices let's say along here. So I'll go back into wall again. And I'm not going to be too precise about it, in fact I'm not going to be precise at it at all. And I should have turned off chain, which I'm going to do.
And just going to put another one in here, like so. So, those don't look too equal, do they? And they shouldn't. So, what we're going to do now is make them equal. So, I'm going to come in and hit Modify. And then off the Quick access toolbar, I'm going to find aligned dimensions and I"m going to pick them. And in this case, I'm going to pick the middle of this wall and this wall, that wall and that wall and then pull up. Now you'll notice that these walls, they're all a little bit different, but there's also something kind of unique here.
There is a slash going through the equal sign. Go ahead and click on that and you'll notice that the walls automatically jump into being equal, and you can lock them down like so, and hit modify. And there you go. So when you lock down these dimensions, what you're basically saying is that these walls are always going to stay in alignment. Of course, you can also get rid of the alignment by going ahead and deleting it, but the walls will stay exactly where they're at.
So the offset command is very useful in using existing geometry to go ahead and place additional walls at specific instances of distance. And you can use the multiple equal of dimensioning to basically define a space without doing the math to figure out what the distances are between walls.
