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.
We've seen several example of tags already in many of the movies in this training series. In this movie, we will actually look at creating the tags. The tag basically asks the question of the object and then reports the result to the symbol onscreen. The same designation is often included in a field on the schedule, so that cross-references can be made. We can tag all sorts of objects, doors, windows, walls. So let's look at a few examples. I am in a file called Working with Tags. It's in the Chapter 10 folder. I am going to click on the Annotate tab, and on the Annotate tab we have a Tag panel, and we are going to start with the Tag by Category button.
You can see the shortcut for that is TG. Now, the way Tag by Category works is as you move your cursor around the screen, Revit will identify the item under your cursor and choose the appropriate tag for you. So you can see that if I am over a wall, I get this diamond tag. I get the pillbox if I am on a door. If I am over here on a wall, I get this hexagon. We've already got tags in our rooms. So typically if an object is already tagged, Revit will ignore that object. It won't add a second tag.
Some items will highlight, like this railing, but if I were to actually click on the railing and try and tag it, I would probably get a message telling me that I don't have a railing tag currently loaded. The same might be true for floors or other objects. So Revit will let you tag just about anything, but in order to tag something, you actually have to have that tag loaded. Now, before I go ahead and actually click to create this tag, let me point out one more thing. Notice that this tag is actually being attached to the object with a short straight leader. This is all controlled right here on the Options bar.
So sometimes you want tags to be associated with the objects for the leader and other times you don't. So what I am going to do is actually uncheck the Leader here to create door tags, and then I will go ahead and click on the various doors. Now, I'm going to zoom in and show you that when the doors were added, they were numbered at that time. So by tagging, all we are really doing is, again, the tag is simply asking the question of the door, "hey door, what number are you?" and it's reporting that information in the tag.
So it's not assigning the number at this time. It's not changing the door in any way. Now, this particular door doesn't actually have a number, so you see a little questions mark appears, and we can remedy that easily enough. Now, if I came over here to a window, in this case it looks as though the two windows have the same designation. Well, tags can report any property in the object they're tagging. In the case of the door, the tag is reporting the Instance property for the door number.
It's called simply the mark. In the case of the window, it's reporting the type designation for the window, which is called the type mark. So that's why these both share the same number, because what it's telling us is these are both type 22 windows. So, for example, if I were to click Modify, select my window, and from the Type Selector, choose a different size, you will see that not only does the size and shape of the window change, but the type designation changes as well.
So depending on how the tag was defined and what property it's designed to look for, you may be seeing a type property, or you may be seeing an instance property. Now, the way that I am adding these tags is fine. I mean, it's moving along pretty quickly, but there is actually a much faster way. Right next to the Tag by Category button is a Tag All button, and this is actually, if you pause a minute and wait for the tooltip, you can see it's actually Tag All Not Tagged. So what it does is it won't, again, do redundant tags. It won't retag anything that's already tagged, but if you clicked this, you will get a dialog box and it will list for you all the categories of tags that are currently loaded in the project.
So my project has door tags, and it has property line segments and room tags and window tags, but you could see that it doesn't have like floor tags, or it doesn't have railing tags, as we talked about a few moments ago. I am going to choose Door Tags, because that's what I'm interested in tagging. Let's go ahead and move this out of the way and see if there's actually any doors. There are a few doors that still don't have tags. So when I click OK, you'll see that it will add tags to those missing doors in one shot. Now, we have several windows that don't have tags. So if we repeat that again, and this time highlight the Window Tags and click OK, you see that tags will get added to all the windows, and clearly that's much faster.
Now, even though we have Tag All Not Tagged, some tags you may still choose to do manually. For example, I am going to go back to Tag by Category, and I want to talk about wall tags next. Now, with the wall tag, you typically don't want to attach that directly to the wall. You typically want a leader associated with that. So I am going to go ahead and check the Leader box, and then I can come in here and select my walls, and you'll see the tag appear with a leader attached to it.
Now, if you think that leader is not quite the right length, we can actually adjust it. How about 3/8 of an inch? Make it a little shorter. I am using my Tab key here to highlight the wall, so I don't want to tag the toilets. But I can kind of move around and make these changes. Now, why are all these tags blank? Well, it's a similar kind of reason why the window tags were all the same number. The wall tags are looking at the Type Mark property, and it turns out that most of the walls, if not all the walls, in this project don't have anything assigned yet for that property.
So I've added a few tags just so we can see what's going to happen. When I select one of these walls now and edit its type, scroll down and look for the Type Mark property. If I type something in here, like A1, and click OK, that will instantly fill in in all of the instances of A1 wall throughout the project, which is everything I've tagged, except the plumbing wall that we built-in a previous movie. Let me go ahead and select that one. Edit Type. Let's make this a B1. Click OK.
And that would fill that in. If I had another plumbing wall somewhere else in the project, it would get that designation as well. So we've filled in the missing wall designations, but we still have this one door that needs to be dealt with. Pretty simple. All we have to do is select the door, and remember the doors don't use a type mark. They use an instance mark. They are using just the Mark property. So here it is right here. And all I have to do is type in a number. Now, I am not sure exactly which number. This is a case where, because each door is unique, if I use a number that's already in use, Revit will complain, like let me deliberately use one that we've already got.
So it will tell me, "sorry, you can't do that. We've already got that number." So unless I'm looking at a door schedule, it might be difficult for me to know exactly what number to assign here. So I am going to just play it safe and I will put in something like 20, which looks like it's okay. But I probably would want to go to a door schedule at some point and check out all my numbers, and maybe I don't want a big gap between my last door and this door, between say 15 and then 20, with no numbers in between used. But as long as you're not using the same number over again, you can put in just about any number you like.
So that's how you add tags. Use Tag by Category to add them manually, one at a time. You can use Tag All Not Tagged in cases like door tags or window tags, where it makes sense to do so, where you would want to just quickly create the tags for all those objects. For things like wall tags, where you want to add the leader, you might want to have a little more control, place them yourself. So there it makes a little more sense to do Tag by Category and place them one at a time.
