Join Paul F. Aubin for an in-depth discussion in this video Creating Revit links, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] In this movie, we're gonna create a link to another Revit project. Now, there are a few common scenarios where you would choose to link one Revit project into another. Some of the most common ones would be when you're working together with another discipline. So, if you're the architect and you're creating your model, you might send it off to a structural engineer or an MEP engineer to do the engineering work. They would work in a separate Revit project, and then you would link those projects together to coordinate the different discipline with one another and make any appropriate changes. Another common scenario is in a multi-building campus.
So, if I have Building A and Building B, and I want 'em on the same site, we'll probably set up Building A and B in their own separate Revit projects, and then link them together again for coordination purposes. So, in this example, I'm gonna demonstrate the second one. I'm gonna link in a small outbuilding and place it on the side relative to my current office building. So, the process is fairly simple. You go to the Insert tab, and you click the Link Revit button. The first thing is to select the file that you want to link. So, in this case, I'm gonna select this Shed building here.
And then, down at the bottom, you choose how you want it positioned in the host Revit project. So, different options are Center to Center, Origin to Origin, and so on. Now, honestly, in this case, it really doesn't matter what I choose because whatever I choose I'm probably gonna have to move the building initially anyway. But in the scenario that I mentioned first where you were coordinating two disciplines, Origin to Origin is probably the most logical choice because the chances are that both the architect and the engineers are gonna be using the same origin point. But in this case, with multiple buildings, it really doesn't matter, so I'm gonna go ahead and select Origin to Origin and click Open.
And, of course, as you can see, that just placed it right on top of the other building, which is probably not where we intended it to go. Move your mouse over here to select it. If it doesn't highlight and you're not able to select it, then that means that you have Select Links turned off in your interface. So, to turn those back on, you've got an icon for it down here. So, if there's a little red X on there, you won't be able to select it. And the other option is to use this drop-down right here, and you want to check Select Links. So, you have to make sure that Select Links is checked or that the little red X is not appearing, and then you'll be able to select that linked file.
Now, I'm just gonna click Move, and pick a start point. And turn off Constrains, so I can move it freely. And then, I'm just gonna kinda move it off and to the right. Now, it doesn't really matter where you put it exactly, but feel free to type in an exact value if you want to. But let's just pretend that that's the location of the Shed building relative to the current Office Building. Now, where exactly do links show up? Well, one place is in Manage Links. And there's the Shed building right there, and you can see it's currently Loaded. The other place that it shows up is if you scroll down on the Project Browser, there is a Revit Links branch here on the browser.
And if I expand that, you'll see the Shed file listed. It's got a blue arrow next to it. The blue arrow indicates that that file is currently loaded. Now, let's go ahead and open up the 3D view. I'm gonna just click the default 3D view icon here. And this is another way that you can see the Shed file right there. Now, I'll zoom in slightly to get a better look. Now, let's say I wanted to Modify the Shed file. There's a slight limitation that you need to know about working with link files in Revit. It's not possible for you to open both the Office Building and the Shed at the same time in the same copy of Revit.
You could have User A working on the Office Building on one computer and User B working on the Shed building on a second computer. That works perfectly fine. But if they're both trying to be opened on the same computer, Revit will not allow that. So, if I try to go to Open, select the Shed, and click the Open button here, Revit will tell me as much. It'll say I'm sorry, but before you can open this file, you have to unload it. Is that okay? I'll say yeah. Then, it'll say are you sure? Because you can't undo this. And I'll say yeah I'm sure. And I'll click OK again.
Alright. Now, if I switch back to my Office Building here on the 3D view, notice that the Shed now has a big red X next to it. And, of course, it's disappeared. So, that's what it meant by unloading the link. Another way you could see that is if you go to Manage Links and you select the Shed, it says the status is Not Loaded. So, it still exists in the file, it's just not currently loaded. Let me go back to the Shed. And let's make some changes, something that'll be obvious and noticeable. So, I'll select this window, copy it over, maybe select this door, make it a little larger, and a double door.
So, both of those things should be pretty noticeable. I'm gonna go to the Application menu here and choose close. And then, when it asks me if I want to save, I will say Yes. Now, back here in the Office Building, I want to simply Reload the file. Now, once again, I could go to Manage Links and do it there. Or, it's actually a little quicker to just right-click directly on the Shed entry here and choose Reload. When I do, the file will reappear. And as you can see, it now has three windows over here and a double door there. So, that's the basic workflow of linking together two Revit projects.
You just simply link one into the other, and then if changes occur, you just refresh the link. And you'll see the latest changes. I should mention that with Revit Links, if you close the file and then you reopen tomorrow, if somebody's continued to work on the Shed while you were away, Revit will automatically load the latest version of the Shed that first time you open. But then, from that point on throughout the day, you'd have to use Manage Links to Reload it.
First, get comfortable with the Revit environment, and learn to set up a project and add the grids, levels, and dimensions that will anchor your design. Then author Paul F. Aubin helps you dive into modeling: adding walls, doors, and windows; using joins and constraints; creating and mirroring groups; linking to external assets and DWG files; and modeling floors, roofs, and ceilings.
Paul also shows advanced techniques for modeling stairs and complex walls, adding rooms, and creating schedules. Finally, discover how to annotate your drawings so all the components are clearly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.
