In Revit Architecture 2011 Essential Training, author Paul F. Aubin shows how to create compelling architectural designs using the modeling tools in Revit. This course covers the entire building information modeling (BIM) workflow, from design concept to publishing. It also covers navigating the Revit interface, modeling basic building features such as walls, doors and windows, working with sketch-based components such as roofs and stairs, annotating designs with dimensions and callouts, and adding 3D geometry. Exercise files are included with the course.
Boundaries are required in order to generate the area and volume of a room. Without boundaries, rooms will simply be referred as unbounded and they will show that blue generic rectangular shape that we saw in the adding rooms movie. Many elements can be room bounding in a Revit project. These include walls, floors, ceilings, columns, and we do have control over which elements in our project are actually set to room bounding. So let's go ahead and take a look. I am in a file here called Room Bounding. It's in the Chapter 9 folder. And if I select any wall in my file and look at the Properties palette, with this wall selected and I scroll down, and I can see that the Room Bounding property has a check mark next to it.
If I were to uncheck that, it would remove the bounding property from the room. So I am going to come over here and pre-highlight bedroom number 5. You will get the hang of it. It takes a little practice, but you just kind of move your mouse to where you think that little X is, and then it will highlight, and then you can select on it. Notice that the shape of the bedroom goes to the inside of the closet. Now, I could certainly add a room in the closet to make a separate room called closet, or in some cases you may not be interested in actually having that be a separate room. Maybe you're going to do a marketing plan to print in a brochure, and you don't really want to call out each and every one of the little small spaces.
So you could actually take these two walls over here and turn off their Room Bounding property and thereby have the room flow in and include the space of the closet. So if I select the first wall, tab, pre-highlight the second one. Before I click, I want to press my Ctrl key to add to the selection and then click. I've got both of those walls selected, and then I will scroll down and I'll turn off Room Bounding. Now, if we go pre-highlight the room again and select it, you will notice now that the room flows right into the closet and completely includes the entire area.
Now, that does change the square footage that would be reported for the bedroom object. I forgot to show it to you before we started, but it's currently 171.89 square feet. So let me do it this way. Let me undo, select it again, and now you see it was only 150 square feet. So it definitely impacts the way that Revit calculates that room. So when you're deciding whether or not to make a certain element room bounding, that might be one of the things that factors into your decision is whether or not you want to actually include that in the square footage count or not.
Be careful when you change the Room Bounding property. If you already have a room, like say I wanted to do that same trick here with the master bedroom, but you already have a room in the small closet and you come in here, and you change the Room Bounding property to non-bounding. When I accept the change by shifting focus away from the Properties palette, I will get this message that comes up from Revit and if you read through the whole message it's basically telling me that I have two rooms now that are in the same spot.
It's even offering to delete one of those rooms for me. Now, let's say that I was a little nervous about deleting a room. I go "I don't want to delete anything. What are you talking about?" So I click OK. Let me show you what's actually going on here. If I come in here and highlight, actually the room is flowed through now, ignoring that wall, but there's actually two rooms in that same spot. So if we were to actually take this one and delete it, now we are going to get another kind of error when I delete it, and I will talk about this error in just a minute.
You noticed how the tag disappeared in the linen closet. So that was the room that we deleted. You may think you've actually deleted it, but what it's telling you in the warning here is we've deleted the room from the model, but it still remains in the project. In the adding rooms movie, I mentioned that rooms behave just a little differently than other model objects. And this is one of the ways that they behave differently. You can't just delete a room in the model; you have to actually delete it deliberately. So they do this on purpose, because sometimes people like to actually create the rooms first in a list and then go and add those rooms that they've created in a list to their projects.
So if you get a program from your client, and it lists out all the spaces they need, you might predefine what all those spaces are and then come in and add them to your floor plan. So just exactly how would we deal with that room then if we have that extra room? Let me show you here. There we go. There is actually still a room there. So let's go down here on my Project Browser and open up the Room Schedule. Now, we are going to talk about adding schedules in a future movie. So right now I have just provided a schedule for us, and if you look, here is all the numbers, here is all the names, and all the areas, but notice that room number 15 is listed as not placed.
So even though we deleted it in the model, room 15, that linen closet, still exists in the project, and we could now place it somewhere in the project, but until we place it, it will list here as not placed. It won't report any kind of square footage. So again, if I was building a program of spaces and I wanted to add up several rooms ahead of time, and then later people could add them to their project. So how would they do that? I can click New right here on the Ribbon to add rooms. So I've just added room number 17. It's also not placed.
If I don't want that room, I can select it and this is how you actually permanently delete it. From the schedule, you click on it and then you click the Delete button. This will warn you, are you sure? We are permanently deleting that room now. I am going to go ahead and click OK. Then what about a not placed room. How would I go ahead and place that? Well, let's go to the floor plan. Let's take this wall and make it Room Bounding again. Now we need a room in that little spot. Let's go ahead and zoom in a little bit there to get a better look.
Before you place the room, the default, if you look at your Options bar, is to create a brand-new room, but if you look right here, this is actually a little dropdown and there's 15 Linen. So that room exists on the list, and if you've got a long list of programmatic rooms, they will all be listed there, and then we can add 15 Linen to our model like so. So those are a few little extra tips and tricks that you need to know about working with rooms. If you delete a room, it's important to remember that it's not actually deleted from your model. You have to actually delete it from the schedule to delete it permanently.
You can always go in and select individual walls or ceilings and floors and turnoff their Room Bounding behavior and adjust the square footage of rooms that way.
