WEBVTT 00:00.000 --> 00:05.400 Hello, and welcome to BIM Model 1 introduction to Revit. 00:05.400 --> 00:09.560 To kick off the course, I would like to first start out by covering a few primary concepts 00:09.560 --> 00:12.700 and terms to make sure that we're all on the same page. 00:12.700 --> 00:15.800 The first concept I'd like to review is file types. 00:15.800 --> 00:22.520 I've downloaded the course files from the Resources tab and extracted the zip file, and this 00:22.520 --> 00:24.000 is what you get. 00:24.000 --> 00:28.280 So within that, you can see that we have three different project types. 00:28.280 --> 00:34.040 Two of those are associated with Revit, and one is just a PDF here. 00:34.040 --> 00:38.000 First file type I'd like to discuss is a project type. 00:38.000 --> 00:44.360 The project is going to be identified with the extension .RVT, and that's going to be 00:44.360 --> 00:48.080 the main home base for pretty much everything that we do in Revit. 00:48.080 --> 00:54.840 So similar to AutoCAD where you have a .DWG file as your primary file type, that's what 00:54.840 --> 00:57.960 our .RVT file is going to be. 00:57.960 --> 01:02.840 The other one that we're going to use considerably in this class is a .RFA. 01:02.840 --> 01:09.680 And .RFA is how we identify Revit families, and Revit families are going to be items like 01:09.680 --> 01:15.200 doors and windows, and in the example that you see here, we have a laboratory, so a wall 01:15.200 --> 01:19.520 mounted sink here, and then we also have a couple of title blocks. 01:19.520 --> 01:26.080 So it can be any number of things that we use to help develop our Revit model further. 01:26.080 --> 01:31.400 The next concepts I want to cover are the primary concepts for the program itself and 01:31.400 --> 01:35.880 how it operates, and we'll also touch on a few terms as we go through this. 01:35.880 --> 01:39.320 So the first one that we want to talk about, and it's one that gets thrown around quite 01:39.320 --> 01:44.000 a bit, is going to be parametric objects and their relationships. 01:44.000 --> 01:49.120 So whenever you hear the term parametric, what it's really referring to is just an item 01:49.120 --> 01:53.200 that has parameters that we can potentially change. 01:53.200 --> 01:59.320 So if I were to use, say, this double door as an example, this door here, as you can 01:59.320 --> 02:07.600 see through the type selector, is a 72 by 84, and those are parameters that define the 02:07.600 --> 02:10.120 width and the height of the door. 02:10.120 --> 02:15.120 The family itself is called door double glass, so what we're looking at here is a double 02:15.120 --> 02:18.200 door that has glass within it. 02:18.200 --> 02:23.840 Some of the parameters more specifically will be located within the edit type dialog, 02:23.840 --> 02:29.960 and we will go through all of this in great detail in our user interface lesson. 02:29.960 --> 02:34.400 But you can see the parameters that we're referring to that make this family parametric 02:34.400 --> 02:40.480 are going to be the width and the height, and then also there's some material parameters 02:40.480 --> 02:47.080 and other dimensional parameters that identify the thickness of the trim and the width and 02:47.080 --> 02:50.800 where they're located. 02:50.800 --> 02:56.200 The next concept I'd like to cover is called bi-directional associations, and this is really 02:56.200 --> 03:01.740 just a fancy term for if you change something in one location, it changes everywhere else. 03:01.740 --> 03:07.600 So one of the common misconceptions about annotations within Revit is that they're really 03:07.600 --> 03:12.720 just a tag that you input information to, but really what they are, is they're a tag 03:12.720 --> 03:16.640 that relays information back to you based on the element. 03:16.640 --> 03:22.280 So this is a room tag that shows us a number and an area, and if I were to say pick the 03:22.280 --> 03:31.880 room element here, you can see that those parameters are actually part of the room itself, 03:31.880 --> 03:42.920 and if I were to change any of those, say the room number here, it'll actually change 03:42.920 --> 03:44.400 within the room itself. 03:44.400 --> 03:53.800 So if I put it back to 112, it'll update on the tag. 03:53.800 --> 04:00.040 So the bottom line here is if things have this bi-directional association, the beauty 04:00.040 --> 04:04.440 of it is, you change it once, and all other elements associated with it will change as 04:04.440 --> 04:05.440 well. 04:05.440 --> 04:10.560 This is probably one of my favorite Revit concepts here, and that has to do with the 04:10.560 --> 04:12.000 user-defined rules. 04:12.000 --> 04:17.120 And so we'll use this a lot in our day to day work because sometimes we'll be fitting 04:17.120 --> 04:25.080 out a space like a mechanical room or maybe a lab support room that has a specific dimension 04:25.080 --> 04:26.080 that's required. 04:26.080 --> 04:30.840 And so what I'll do is I'll draw a dimension. 04:30.840 --> 04:37.760 And then if I said that I always want this wall to be 11 feet or 11 foot 11 and 11 16th 04:37.760 --> 04:43.160 in this case, from grid line three, I could lock that dimension. 04:43.160 --> 04:49.000 And no matter where either grid line three moves or this wall moves, that dimension is 04:49.000 --> 04:53.040 always going to stay at that 11 foot 11 dimension. 04:53.040 --> 04:57.360 And there's other types of user-defined rules that we could implement as well. 04:57.360 --> 05:03.480 Some of those could involve even using formulas to develop how things are going to react 05:03.480 --> 05:09.200 to each other or whether an array has a certain number of items associated with it. 05:09.200 --> 05:15.040 And those are items that we'll cover as we progress through the course. 05:15.040 --> 05:20.800 So a few terms that I'd like to cover involve some of the items that we use within the program. 05:20.800 --> 05:26.240 So in this case, we would be looking at a view here, and a lot of times I'll call this 05:26.240 --> 05:29.920 a floor plan view or a plan view as we go through the video. 05:29.920 --> 05:34.400 So if you hear that, it should trigger that we're in a floor plan view. 05:34.400 --> 05:38.040 Another one that you'll hear a lot is we'll talk about levels. 05:38.040 --> 05:41.600 And when we're talking about levels, we're not necessarily talking about level one level 05:41.600 --> 05:45.000 two room for or parapet or whatever it may be. 05:45.000 --> 05:51.200 But we're actually talking about the physical element that makes up the levels that determine 05:51.200 --> 05:53.720 the height of these different items here. 05:53.720 --> 05:59.280 So you can see here level one is an actual data element that we will use. 05:59.280 --> 06:04.640 And it happens to also create our level one floor plan for us. 06:04.640 --> 06:08.760 So just to keep it clear and make sure that we're all on the same page, when we're talking 06:08.760 --> 06:13.600 about levels, we could also be talking about the data element or we could be talking about 06:13.600 --> 06:19.760 the actual plan view that we're looking in. 06:19.760 --> 06:24.960 Another one, which is a pretty important concept to understand here, has to deal with the 06:24.960 --> 06:28.800 hierarchy of the elements within Revit. 06:28.800 --> 06:32.480 And this can be a little difficult to wrap your head around at first. 06:32.480 --> 06:36.960 But once you get it, it really clicks and it helps you to be able to modify elements 06:36.960 --> 06:40.760 as you go through and develop your project. 06:40.760 --> 06:46.040 So everything within this program works under this hierarchy. 06:46.040 --> 06:50.400 Every element that you see here is part of a category. 06:50.400 --> 06:55.840 So if I were to use walls as an example, the category that we're dealing with here 06:55.840 --> 06:57.640 is walls. 06:57.640 --> 07:00.920 The family that we're working with is basic wall. 07:00.920 --> 07:03.240 You can kind of see the pop up there. 07:03.240 --> 07:11.280 And then the actual type that we're dealing with here is interior 4 and 7, 8's partition. 07:11.280 --> 07:15.200 And the instance is the object I have selected. 07:15.200 --> 07:18.560 So when we're talking about the hierarchy of certain elements here, we're going to go 07:18.600 --> 07:25.840 with category, family, type, and instance. 07:25.840 --> 07:31.720 And this is really important because it actually determines how elements get modified through 07:31.720 --> 07:32.720 the project. 07:32.720 --> 07:38.800 So if an object is modified at the category level, then the family, type, and the instance 07:38.800 --> 07:41.040 all get edited as well. 07:41.040 --> 07:43.760 So a good example here would be a door. 07:43.760 --> 07:49.800 So if I pick on this door here, this door is part of the door's category. 07:49.800 --> 07:55.640 It is the single flush family and the type is 36 by 84. 07:55.640 --> 08:02.320 So what we have here in this dialog box, which is the properties palette, we have the 08:02.320 --> 08:03.720 instance parameters. 08:03.720 --> 08:11.880 So that means only this one instance will be modified if I change any of these values 08:11.880 --> 08:13.040 here. 08:13.040 --> 08:19.920 If I were to go one level up to the type parameters, which are located here in edit type, and make 08:19.920 --> 08:27.000 a change, then all of the instances of 36 by 84 within this project will be modified. 08:27.000 --> 08:32.000 And this is really important to understand because you could inadvertently make a change 08:32.000 --> 08:34.520 to something that you didn't plan on doing. 08:34.520 --> 08:39.960 So if I were to change the width to say one foot, which is a pretty ridiculous width for 08:39.960 --> 08:44.200 a door, but it's a good example because you'll see it very graphically here. 08:44.200 --> 08:52.600 So if I hit OK, you can see that all of my 36 by 84 doors are now 12 by 84. 08:52.600 --> 08:54.440 And that's throughout the entire project. 08:54.440 --> 08:59.080 So if I were to go to level two, you can see the same thing happened here as well. 08:59.080 --> 09:04.000 The beauty of rev it though is we, just like a lot of programs, we have undo. 09:04.000 --> 09:09.200 And so I can undo back to where I have normal door sizes again. 09:09.200 --> 09:13.240 But the moral of the story here is, if you do have to change door and we'll go through 09:13.240 --> 09:18.200 this process in a later lesson, you're going to want to make sure you use a different type 09:18.200 --> 09:22.080 instead of just modifying one that's already there. 09:22.080 --> 09:26.160 In the next video, we're going to go through in detail and talk about all of the different 09:26.160 --> 09:28.160 elements in the user interface. 09:28.160 --> 09:31.360 And it'll probably answer some of the questions that came up as I was going through this 09:31.360 --> 09:32.360 interaction.
