Creating a construction detail
Video: Creating a construction detailIn this movie I'd like to look at the detailing process in Revit. Not everything that you create in your Revit project will be part of the model. There are many advantages of building model elements because they appear in multiple views. And when you change them, they change everywhere. But not everything needs to show in all views. And so, there are certainly plenty of instances where we have items that are considered construction details that really only show in one place. And the quantity of information that's displayed in those views is at a level of detail that makes it impractical to consider modeling all those elements. Consider things like bolts and screws and flashing and mortar joints and clips and hangers.

Autodesk Revit is one of the most popular building information modeling (BIM), solutions today. This course covers the differences between the various editions of Revit and shows architects and engineers who are new to the software how to use them. Learn how to choose a template; set up the basic levels, grids, and dimensions; and start adding walls, doors, and windows to your model. Author Paul F. Aubin also shows how to create views and documentation that clearly communicate your plans, import files from other CAD programs, and produce construction documents.
Note: The techniques shown in this course will work with any version of Revit, but due to backwards compatibility issues, the exercise files for this course will only work with Revit 2014. Unfortunately, we cannot downsave the files. Please see a Revit 2013 course for usable files.

Creating a construction detail
In this movie I'd like to look at the detailing process in Revit. Not everything that you create in your Revit project will be part of the model. There are many advantages of building model elements because they appear in multiple views. And when you change them, they change everywhere. But not everything needs to show in all views. And so, there are certainly plenty of instances where we have items that are considered construction details that really only show in one place. And the quantity of information that's displayed in those views is at a level of detail that makes it impractical to consider modeling all those elements. Consider things like bolts and screws and flashing and mortar joints and clips and hangers.
None of these items would really give you much benefit to adding them 3-dimensionally in your model. They would just simply serve to weigh down the model and impede performance, without really adding a whole lot of benefit. So at some point you need to stop modeling and begin drafting. And essentially, what we do in a Revit process is we do a hybrid. So it usually starts by building a view, an enlarged view of a certain area that will give us a portion of our model to look at. And then, on top of that view of the model we'll add additional drafting components to complete the detail. I'd like to show you a quick example of that here in this prep station. I'm in the detailing file and I'm in the Level 1 floor plan. And the first step is to create that view, that enlarged view that we're going to then add the detailing to, so I'm going to come up here to the quick access toolbar. I'm going to click the Section tool and then over here on the Properties palette, it defaults to a building section.
I just want to open that up and change that to detail. And I'm going to click two points. I'll click over here to the right, and drag through the counter top to the left. That will create a very small little detail view. I'm going to deselect it and here's a shortcut to open that view. You can just take this little bubble that appears here and double-click it and that will open up the view. Now the crop region needs a little bit of fine tuning here. So let me adjust that a little bit so I can see the full height of my detail and I'll actually narrow it up just a touch and I don't need to see quite that much down below. So I'll shorten it there as well.
Now, the next thing I want to look at is the scale. This section cut got created at 8 inch equals a foot. And that's way too small for a detail. So I'm going to open up the list of scales here. And I'm going to enlarge this scale to 1 and a half inch equals a foot. And that will adjust the view that you see on screen here. You can see of course the level annotation got a lot smaller. This gives me the basic starting point. I have my low height wall here and my countertop here. And now what I want to do is start adding detailed components on top of that. Now, the way that I do that is I come over here to the Annotate tab.
And there's a component tool here on the Detailing panel, it's just called Detail Component. If yours doesn't show here, there's a little drop-down. And it might show Repeating Detail or Legend Component; just make sure you're choosing Detail Component from this list. This behaves much like the 3D component did. Over here on the list, we have a series of choices, so you could see that there are several detailed components already loaded into this file, and I'm going to start with a couple that are already here. There's a light gauge metal channel and a light gauge metal stud. So I'm going to choose the 3 and 5 8ths inch Light Gauge Metal channel and bring that in, I'm going to zoom in down here at the bottom, notice that its going vertically.
I'll just tap my space bar to rotate it 90 degrees and then I want to line it up with the center of the wall and just sort of place it down here towards the bottom. I'm going to zoom back out. Drag to the top, zoom in, tap the space bar twice and place another one up here at the top. Then I'm going to come over here, change to the light gauge metal stud three and five eighths. That shape changes slightly. Let's zoom out again, pan over here, when I come in here, tap the space bar and get it lined up with the center and about near the top of the counter top.
Tap the space bar one more time and do another one right here. Now, you see I'm having a hard time getting it lined up, I'm going to get it close by, like so. I'm going to click the Modify tool and cancel out of the command. Let me zoom in here just a little bit. We have this wonderful tool on the Modify tab called the Align Command. So, I'm going to go to Modify, click on the Align tool right here right about the Move command, and what you do is you pick twice. The first point is your point of reference. So, I want this stud to line up with this stud.
So, my point of reference is going to be the side of the one I want to line up with. That's this guy. Then you pick the edge of the one that you want to align. And you see now that those two are perfectly aligned. Let's do it again I want to line up here and then this guy. And they both move into perfect alignment. So the Align tool is a great way to move and or rotate objects into perfect alignment with some other object that you already have. So those are the studs. Now, I want to add the drywall. Now, if I go back to the Annotate tab and click the Component button, we don't have a drywall component currently loaded in this project. Now, these component families that we're adding are actually just 2D detail component families.
They behave a lot like the other components we were adding, except that these are view specific. They only occur in this View. If you open up any other view of the project, you won't see these objects. And they're 2-dimensional. But there's a whole bunch of them that are included with the software. So I can access those ones that are included right here on the Load Family, just like we did with the 3D components. Here in the US Imperial Library, there's a detail items folder. I'll open that up. And then there's several subfolders organized in MasterSpec divisions, and I'll just find the folder that I need.
Division 9, and then plaster, and gypsum wallboard, and then find the gypsum board here at the bottom. There's gypsum wallboard in Section. I'm going to open that. And if you look over here on the list, not only did this load over here they gypsum family but all of these different sizes. I'm going to use the 5 8ths type and zoom in here towards the bottom, click my first point and start to drag. This is a two-click family. It's what we call a line based family. So you pick once and you go the other end here and you pick again. And it creates the component.
Let's repeat. Let's click our first point there. Come down here. And our next point there. So what that does is it draws the drywall, complete with the stippling, it gives you all of the detail information about the drywall. It just does it with a 2-dimensional component, so you're not actually modeling the drywall, you're just, you know, representing it here 2-dimensionally. Let's do a few more components. Component tool > Load Family > Detail Items. I'm going to go into Woods and Plastics, Then Millwork, and then I'm going to take this mill work, standard mill work in section. This is just a standard wood board, and I'm going to open that. Now, this one has a bunch of sizes available if you scroll through the list. And so what you can do is just sort of scroll through here and find the size you want.
I've got a 5 inch partition here. I'm going to choose a 1 by 6 which will be just a little bit wider than that. Click OK. And this is going to give me a nice wood cap that I can use up here at the top. I'm going to tap the space bar to rotate it. And I'm going to place it right there. And now I have this nice little wood cap at the top of my wall. Okay? Again, return to the Component tool. Let's Load Family. And I'm going to bring in one more. I'm going to go to Detail Items. And then I'm going to go to Furnishings. And then, under Case Work.
In case work, we have a Countertops folder. And there's a Counter top in Section Family right there. I'm going to open that up and its pointing opposite of the way that I want so what I'm going to do is just get it lined up with the top of the countertop here and click. Cancel out of the command, zoom in a little bit. Now, I'm going to mirror it on itself. So I'm going to select this object come up here and click the Mirror tool on the Modify tab. And make sure you uncheck the Copy check box right there. When I do that, it will mirror and delete the original. So it'll, it'll mirror the actual object instead of making a copy of the object. Now, I'm going to move it from this point over to this point. And then you can either stretch this grip to lengthen it or, actually, your Align command will work again here.
If we go to align and I pick the leading edge right there and then the edge of this, it will actually stretch it out to match the length that we have there. So you can see where I can use the underlying model to help me build these detail components on top. Now, none of this geometry that I've added on top actually appears in the model. It's all just 2D geometry that we've layered on top, and you could certainly add other things. You could add caulking in there, you could add wood base at the bottom, and you could add blocking over here. All of those components can be found in that detailed items library, but I'm going to go forward here and just add a few notes to kind of finish up this detail. So if we go to the Annotate tab, we've got our Text tool right here. Now, the Text tool can be created with or without a leader. So the default doesn't have a leader and if I just sort of click right here. (SOUND) And type in a note.
What you want to do is type your note and then click next to it to complete the note. You could see that that will just create the piece of text. Or you can click one of these options here with the leaders. And I'll do this two segment leader. And click where you want to point to. Click where you want the elbow to be, and then where you want the note to go, and then type your note. Don't forget to click Next to it to complete the creation of the note. And you could continue to type additional notes.
And then that first note that we created, it's actually possible to select it. And then up here on the ribbon, we can add a leader after the fact. So I'm going to click this little plus sign here for a leader on the left and then I could take these little grips and I can point to the location where I want that leader to go. And you can fine tune the position of this text and you can even. Add a little elbow here like so to make it a little more consistent with the rest of the notes. So if necessary you can add other notes and dimensions and other detailed components to finish up your detail. But the basic process of crating a detail in Revit usually involves making a section cut somewhere in the model to get you started. And then overlaying on top of that a series of 2-dimensional detail components and text notes.

Here are the FAQs that matched your search "" :
- Q: Will Revit 2014 files work in a previous version of Revit? Will the exercise files for this course work in Revit 2013?
- A: Revit file formats are not backwards compatible. A new file format is introduced with each new release. Newer versions of Revit can open older version files without issue. However, files will be upgraded to the latest file format during the initial open. Once saved in the current version, there is no way to save them back to a previous version. Therefore, it is important to consider this issue carefully and discuss it with all project team members before beginning a project. For example, it is not possible for the architect to use a newer version of the software than the consulting engineers and vice-versa. All members of the team must collaborate using the same version/file format. This course was authored using Revit 2014. Therefore, its exercise files can be used with any flavor of Revit (Architecture, MEP, Structure, or LT) 2014 and later. Files cannot be opened with versions 2013 and prior.
