I have a site with three surfaces. The existing conditions, which I have set to Contours (background); the proposed grading, set to Contours (design) and the third surface, which represents the part of the site which will be underwater, I want in a third style. None of the out-of-the-box styles suit my needs, so I copied the Design style, intending to edit it, to change the appearance - layers, colors, etc. On the display tab of the surface style dialog box, the only thing I am able to edit are the names of the component type. Clicking on the layer names, colors, linetypes, etc. does nothing.
