My boss wants to see the topography contours displayed on an AutoCAD drawing such that the lines display on a gradient scale. My shapefile has elevation contour lines with a contour elevation number assigned to each one. So I can sort them by unique values from lowest to highest and then symbolize them with a color ramp. This makes a nice display and tells the story at a glance.
But we want to use this data as a background layer in an AutoCAD drawing and I have no clue how to export it to AutoCAD and retain the symbology.
If you share it as a web layer to ArcGIS Online, you can access from AutoCAD using the free ArcGIS for AutoCAD plug in. The latest version is currently in beta, but it is vastly superior to the older version.
The beta site also has tutorials and videos that show how to use it. Once your symboloize shapefile is shared online, you can access it through the plug-in.
