Add information to an existing ArcGIS layer

00:03

In Civil 3D, you can add information to an existing ArcGIS layer and then perform a Save Back,

00:11

so that any changes you make in your model also update the feature data in ArcGIS Online.

00:17

With Civil 3D open to the appropriate design project, begin this example by placing the correct geometry in your project model.

00:26

To do this, edit your model.

00:29

For this example, draw a new sewer line in the model.

00:33

From the ribbon, Home tab, Create Design panel, select Feature Line > Create Feature Line.

00:43

The Create Feature Lines dialog box appears, where you can specify the feature line settings.

00:49

Check to make sure the site where you want to place the feature line is correct,

00:53

the proper feature line Style is selected, and the correct Layer to house your new feature line is specified.

00:60

Click OK.

01:02

Draw the new sewer line, then select it and right-click.

01:06

Here, you have the option to move the new geometry you created to an existing ArcGIS layer in your project.

01:14

Select Move to ArcGIS Layer.

01:17

The Move to ArcGIS Layer dialog box opens.

01:22

This is where you can move the objects you added in Civil 3D to the ArcGIS layers that already exist in the drawing.

01:30

Expand the Destination ArcGIS layer drop-down and select SMWS_SewerMains.

01:37

Ensure that the Selected objects include the Feature Lines, and then click OK.

01:43

Select the new sewer line again.

01:46

Right-click it and select Properties.

01:49

Scroll down in the Properties palette to edit the GIS attributes in your model.

01:55

In the PIPEDIAM field, change the pipe diameter to 24, and, in the PIPELEN field, change the pipe length to 750.

02:05

Click CLOSE.

02:07

Now that the feature line attributes match in Civil 3D and ArcGIS,

02:12

you can populate the ArcGIS attribute data from directly inside Civil 3D by performing a Save Back.

02:20

On the ribbon, Insert tab, ArcGIS panel, click Data Source Manager.

02:27

The Data Source Manager opens.

02:29

Here, you can remove ArcGIS datasets from a drawing, refresh datasets from ArcGIS, and save back changes to ArcGIS.

02:40

In the ArcGIS Data Source hierarchy, disable all the data source options, then enable only SMWS_SewerMains.

02:49

Then, click Save back.

02:51

A confirmation dialog box appears, prompting you to continue the command.

02:57

Click Continue.

02:59

A loading dialog displays the progress, and when it is finished, a success notification appears.

03:06

In ArcGIS Online, you can see that all the new geometry you added to the model is there.

03:12

Right-click it, then scroll down to see the feature line attributes.

03:17

The pipe diameter and elevation that you entered in Civil 3D are there.
