Surface Settings Dialog Box
Use the Options > Element Attributes > Surfaces command to open this dialog box.
The pop-up list at the top of the dialog box displays the surfaces available in the Project. At the top of the pop-up list, you will see the name of the currently selected surface, and icons indicating whether this surface has a Vectorial Hatching and/or a Texture associated with it.
The Preview picture changes dynamically as you work in the Surfaces dialog box, so that you can see the effects of your settings. The Preview gives you an idea of what the chosen surface will look when rendered, depending on the rendering engine used.
Engine Settings: Choose a rendering engine from the list.
Important: All surfaces are specific to the engine for which they are set up. If you change a surface parameter for one engine, those modifications will not take effect for the same surface parameter if you switch to another engine.
