Edge 
Edge annotations are available in 3D. You can add edge annotations to any 3D model. Then, you have the option to export those annotations as a DXF file.
Note: The edge annotation is only available in 3D.
If you’re having trouble navigating the 3D model to get a good view of the point you want to select, try double-clicking on the model. This will center the camera on the point that you double-clicked.
Exporting your edge annotations
When you've completed line work on your map, you can export the data into a DXF file for AutoCAD. To access this, select Export in the bottom left corner of the plan and select Edge Annotations.
Choose the File Type and Coordinate System, then click export.
