- [Instructor] In this video, I want to show you
how we can create Revit topography from Civil 3D surfaces.
So I'm going to start here in Civil 3D,
and this workflow does require BIM 360.
So I'm here, looking at my BIM 360 homepage.
And I am logged into my account and project.
And I'm logged in as my user Shad.
And I'm going to open up the drawing
that has the surfaces in it that I want to convert.
And it's using Desktop Connector, of course,
to download that drawing and open it up here in Civil 3D.
Now this file has some X refs in it
that the designer was using to create the proposed surfaces.
And you can see that Desktop Connector just gave me
a warning about that,
saying that it couldn't find those files.
But that really won't affect the work
that we're going to do here.
So it was safe for me to ignore that warning.
This is another similar warning
about the same sort of thing.
So I'm just going to dismiss that,
and I'm going to dismiss this
new unreconciled layers warning, as well.
So neither of those would concern the work
that we're doing here. Now the first thing I want to do
is show you the proposed surfaces
that the designer has created.
So I'm going to click on one of these pink lines here.
Right click, and choose "Object Viewer".
Now that will display a separate viewer window,
and you can resize it, make it a little larger
if you need to.
And then you can just simply click
and start to drag, and orbit this thing in 3D.
And up here, there are some different view modes.
So it typically defaults to "3D Hidden".
The last time I used it, I had switched it to "Conceptual",
which I think looks a little bit nicer.
But you're welcome to go through some
of the other modes here as well.
But if you roll your wheel, and kind of zoom in,
you can see that the Civil Designer
has created surfaces and curbs,
and other features that might be useful
for us to have back in Revit.
So I'm going to close this viewer window.
Now that I understand what this file contains,
I'm ready to export it out to a version
that's available for Revit.
So how do we do that?
Well, we're going to go to the "Collaborate" tab,
and then use this "Publish Surfaces" tool right here.
So that will display the "Publish Surfaces" window.
You uncheck anything that you don't want to include
in the export, so I'm not going to include
any of the existing conditions.
I'm only going to include the proposed here.
And then down at the bottom,
there's a "Browse" button here that you can use
to browse out to BIM 360, and locate a folder
where you want to send this file.
So I'll go into my account, and then my project.
Now, let's keep in mind, that the architects
whom I'm going to be sharing this file with,
won't have access to my Civil folder,
so it needs to be in the Shared folder,
where they can access it.
And if you recall that we elevated Shad's permissions
to the "Shared" and "Civil" subfolders in here,
he's able to write the file to that location
without any trouble.
So I'm going to accept the default name here.
And then simply click "Save", and then "OK".
Now I'll get this message that indicates
that it needs to update the style that's being used here.
So I'll go ahead and choose that option.
And so that completes the export.
So we now have an exported surface file
ready for import into Revit projects,
and so anyone that has access to the folder
that we saved it in,
will be able to use the "Link Topography" tool in Revit
to import that data in.
And we'll take a look at that in future video.
