To begin this tutorial, you should already have contour information loaded into ArcGIS Pro.
1. Click on the View tab at the top of the interface, and then select Catalog Pane.
2. In the Catalog Pane, make sure that you have selected Computer. Expand the folders until you have located the specific folder where the contours you wish to export are located. Below, Computer is outlined in red and the contour file (also called a feature class) is shown next to the arrow.
3. Right-click on the contour layer, and a context menu will pop up. Select Export -> Feature Class(es) To CAD...
The feature class you selected may have several sets of contours (called features). You may want to remove some of these because they cover the same area, just with different vertical spacing (called intervals). For each feature you want to remove, click the red x next to the name of the feature. This does not remove it from ArcGIS - it only removes it from the export options.
You may want to add in other features that are on your map. Click the arrow next to Input Features to search for and add other data.
Click on Environments and then on the globe icon next to the dropdown menu under Output Coordinate System.
In the search bar next to XY Coordinate Systems Available, type in the state where your map is located*, then hit Enter to search. After hitting enter it will seem like nothing has happened - don’t worry!
*for non-US maps, coordinate systems vary by data source and project type.
Now, expand the menu by clicking on the triangle to the right of Projected Coordinate System. Expand State Plane, then NAD 1983 (US Feet) and click on the region of the state that applies to your project. Then click OK.
If you are going to be working in this geographic region frequently, you can click the star to the right of the name of the region to save it to Favorites. This saves you the time of searching for it in the future.
Now in the Geoprocessing pane you will see the selected coordiante system shown. Click Run.
When the exporting process is complete, you will receive a confirmation.
Locate the CAD file on your computer and open it in AutoCAD /another CAD program.
11. You should see your contours in AutoCAD. Clicking on a contour should display its elevation value in the Properties panel.
