We can't get too far without the building we are putting our systems into! This video will step you through the process of properly linking an architectural Revit model. We will start by using Origin to Origin as our reference, then we will pin down the link. Lastly we will make sure to turn on room bounding to insure that our spaces will work properly.
- [Voiceover] The first thing we do when we start any mechanical model is we have to bring in an architectural underlay. What I'd like to do in this video is link a structural model and an architectural model. So to get started lets jump into Revit, under projects let's go to new, then I'm gonna grab a mechanical template and I'm gonna click okay. Now, there's two ways to do this. One way is to go to insert and we can go to link Revit, another way to do it is in the project browser if we scroll all the way down to the bottom to Revit links, we can right click on Revit links and we can go new link.
So either way you wanna do it I'm gonna come down here, right click on Revit links and go new link. I'm gonna browse where I'm keeping my files and I'm gonna grab my architectural model. Now notice there's not as many choices for when we brought in our CAD. Files of type will be a Revit file, we have no choice. For the positioning generally you'll always wanna go origin to origin, however if you're using shared co-ordinates you have to know what those co-ordinates are and you can go by shared co-ordinates or project base plan and of course you can put it in manually.
Generally you're gonna go origin to origin. Now let's click open. Notice I didn't really care what view I was in as long as it's not a drafting view or anything other than a floor plan or a 3D view you'll be good. Now a couple things I like to do, the first thing I wanna do is i wanna select our link and I wanna make sure I click on the pin button right here. This makes it so other people can't move it, but a couple things happen when you hit pin, notice down here we have some choices, we can uncheck select links, so if I come over here I can just hover over this link and I can select it, if you uncheck select links notice that you can't select that link, if you uncheck this, now if you click on select pinned elements notice I can't select it again.
If you ever have a Revit model linked into your model and you can't select it, it's gonna be one of these items are turned off. So I'm gonna click on select pinned elements now I can select it. What I'd like to do is select our link. Now under edit type what I'd like to do is click on edit type right here. Let's make sure under constraints that we turn room bounding on. Now for our reference type we have one of two choices similar to AutoCAD we can have an overlay or an attachment.
An overlay means that if we link this model into another model we won't see any links that happen to be in this. If we do it as an attachment and someone links our mechanical model into their model they're gonna see this architectural model as well. Generally the rule of thumb, like AutoCAD, is to leave it for overlay. Now I'm gonna look at phase mapping 'cause this is important. If we go to phase mapping and click on edit luckily we have two brand new models from scratch but what we're gonna have is phases that are in our model and phases from our linked model.
So if the architect has a bunch of phases we have to recognized that and link them with a phase over here. So I have an existing a new construction if I code to phase to link I can click the drop down and I can choose the phase that I want to link our phase with. I'm gonna click okay, I'm gonna click apply, now I'm gonna click okay. Another thing I'd like to look at on links is how it shows up. If we go to manage and if we come over to additional settings and we click our fly out, let's go down to half tone underlay.
Now we can change how that appears. This can change from firm to firm depending on how your plotters out put but my weight, I generally like to go with a weight of one. For my pattern I wanna keep it at no override. I'll apply a half tone but I usually bump it up to about 80%, now I'm gonna hit okay. Notice that our underlay is gonna be darker, any underlay that we bring into our model will be dark now. Now let's go to a 3D view.
Let's go up to our quick access toolbar and click on default 3D view. Now let's go to insert, let's go to link Revit, let's grab our structural model. I wanna go auto origin to origin then I'm gonna click open. Now it says the following nested links will not appear because their reference type is set to overlay in the link so that means, for example the the structural model had our architectural model linked into it and you're get a nested links dialogue, you want this.
Click close. I'm gonna hit escape a couple times. Now what happens is we have a link over the top of a link so if we zoom in really close, we can select our structural link and we can make sure that we pin it. Go to edit type, make sure room bounding's turned on, it means that we can add spaces and they will bind to the rooms that are in the architectural model. Click apply, click okay. Hit escape a few times.
Now we can zoom out. Now what I'd like to do is go to our visibility graphics. If you type vg or click edit over here for visibility graphics notice that we have Revit links. I wanna come down here to Revit links and if we expand each of these what's gonna happen is this like a normal family we have the name of a family then we have the type of family that we have. So for example, I could copy these links around in my model and we'd have architectural one, two, three, four and each of those are gonna have their own properties.
So remember, if you get more than one for each model you can either delete that or you have to find out what happened, someone might have copied a model, I've seen it happen a lot. Now what I want to show is if we go to the display settings and if we go by host view and if we click custom. Now if we go to say model categories and again instead of a host view we go custom, notice that we can turn on or off any kind of items we want only in the linked model, only in this view, and it won't effect our main model.
So keep that in mind when you have links in. I'm just gonna hit okay here. I'm gonna hit apply here. I'm gonna hit okay. And one more thing you can do with a link that I never really like to do but you can do it, is you can bind it to your model. So if I come over to my architectural link and if I select it, I can go bind link but before I do that I wanna go to manage links, so let's click on manage links. Notice that we have architectural and structural both loaded, they're both overlays and here's the path that we have.
The path is relative but if you send these models to someone else they probably will become unlinked. We can reload from, we can unload, we can add another one, or my favorite when I'm in this dialogue is I can go to remove. And remember when we linked the CAD model? If we go to CAD formats and if it's linked that will show up here. Now generally if you link a CAD model you only wanna link a floor plan or that type of item, don't link details.
I'm gonna go back to Revit. I'm gonna click okay. Now I'm gonna select my link and I'm gonna click on bind link, I can include attached details, levels or grids generally I include none of this stuff then I can click okay. It's a huge link so I'm just gonna click no here but you can click yes just to see the results.
