Below are the commands for this ribbon panel. Any commands specific to Civil 3D or AutoCAD/BricsCAD will be noted with the command.
This function gives you a short cut to turning off/on the individual items that make up a surface as shown below. If you have more than one Surface, select the surface you want then choose the items to show or not to show.
So instead of having to go through following process
Pick the surface on the screen
Edit Surface Style
Turn on/off what you need or dont need
This display can stay on at all times and you can turn your Triangles, Major Contours, Minor Contours and Surface Boundaries on/off faster and easier with having to go through Surface Properties or Edit Surface Display.
