Join Paul F. Aubin for an in-depth discussion in this video Establishing shared coordinates, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Instructor] In this video I want to talk about establishing Shared Coordinates. Shared Coordinates creates a relationship between two files so that they know how to link to one another. We can use Shared Coordinates whenever we have multiple buildings on a campus, or when we're going to use the same building multiple times within the same site. And when we establish the Shared Coordinates it will be maintained throughout the life of the project and we'll be able to cross link the files back and forth to one another. So I'm in my Office Building file and what I've got is a link to the Site Plan information here and I've got another link to this little out building over here.
And what I want to do is actually establish Shared Coordinates between all three of these different files. Now, the first step is I'm going to select the first file that I want to set up with the Shared Coordinates, and I'm going to use the Site Plan file for this purpose. So when I select this file, if you look at the Properties palette, you'll see that it is a linked Revit model, and then right here it says Shared Site and it currently says Not Shared. So I'm going to click that button and this will bring up the Shared Coordinates dialog and it'll give me two choices, Publish or Acquire. Now, what this essentially means is you're going to take the Shared Coordinate information, the information that will record where each file needs to be positioned relative to the other file and it's going to record that information somewhere.
Now, if we Publish the information, we're going to take the information from the current file, which is the Office Building, and we're going to push it to the Site Plan file. If we say Acquire, it'll do the opposite, it'll take the information from the Site Plan and it will bring it forward to the Office Building. Now, you could do either one and successfully set up Shared Coordinates. But, in my opinion, the Site Plan should always be sort of the source of the Shared Coordinate information. So, in this case, since I'm in the Office Building and I have the Site Plan selected, I want to actually read the information out of the Site Plan, so I'm going to Acquire the coordinate system from the Building Site Revit file.
Now, I could go right to Reconcile and complete the process, but if you look down here it says Record the selected instance as being at Position and then it suggests Building Site Internal. Now, Internal is just a default name that Revit gives to this saved information, and you can click this Change button here and change that. You could Duplicate it, make a copy of it, or you could Rename it. I'm going to rename it because I don't like Internal, that's not really descriptive enough for me, so what I want to do is describe what this position means.
And I'll call this Site Position and click OK. So I've just changed that name, I'll click OK and it verifies that here and now I'll click Reconcile. So now it'll say the Shared Site for this selected model is called Site position and that's just the name I gave it. So now I'm going to deselect that and I'm going to select this Shed building and repeat the process. And what'll happen is that this time these two files already kind of know about each other, so it's going to ask a slightly different question.
And it's saying do you want to record the current position of the Shed as internal and that's going to modify the link, or do you want to move it to some existing location? So what I'm going to do is record that current position, I'm going to click Change, and again I'm going to rename Internal and call that Shed position and click OK. OK again and now I'll click OK one more time. All right, so at this point I have created Shared position for the Shed and another Shared position for the Site, I now need to save that information.
In other words, just do the Save command. When you do that, it's going to tell you that the locations in the link files have also changed. So right now it's saying you've changed the current position in the Building Site file, what do you want to do? The only viable option is to save it. If you choose either of these other two you're basically undoing what we just did, so you want to click Save here. Then it'll display the same message again but if you read it carefully you'll see that this time it's talking about the Shed file. So we have to save that one as well. So what we just did was we saved three files. We saved the Office Building file that we're currently in, we saved the Site Plan file, we saved the Shed file, so now what? Well, now we've saved Shared Coordinates now I want to show you one of the benefits of using Shared Coordinates.
Now you may recall, from a previous video, that I can't have both the Office Building and the Site open at the same time in the same session of Revit. So what I'm going to do is do ctrl w to close the current file. Now I'm going to go to Open, and I'm going to select my Building Site and open it up. Now that takes me to a Floor Plan level, let me just come over here and click curly bracket 3D and open up the 3D view. So, what I'm going to do now is go to the Insert tab, and choose Link Revit.
I'll select my Shared Coordinates file. And instead of using Origin Origin, Center Center, any of those, this time I'm going to use By Shared Coordinates. And what that will do is it will trigger it to use the saved coordinate system that we just created. Now it's going to tell me that I've got a nested link for the Shed and I'm just going to ignore that, that's fine, I'll click Close, and notice what happened with the Office Building. It came in in exactly the correct location. Now I'm going to repeat the process, I'm going to select the Shed, right here, click Open and because it's got Shared Coordinates as well it came in in exactly the correct location.
So, one of the huge benefits of Shared Coordinates is once you've set them up, all the files know what to do. In fact, if I opened up the Shed file, and linked in the Office Building and the Site Plan, they would know where to go as well, and all three files are fully aware of one another. So, this is a great way to set up and manage a collection of multiple files. Particularly when you have multiple buildings on the same campus, setting up Shared Coordinates is a great way to go and it helps you maintain the positioning of all the files seamlessly.
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.
