Mesh symbols contain only one symbol layer, a fill symbol layer. When a mesh symbol is applied to a multipatch feature, the fill symbol layer can be a material fill or procedural fill. When a mesh symbol is applied to a 3D object scene layer, the fill symbol layer can only be a material fill. Procedural fills rely on a rule package to define its symbol properties. The rule package associated to a procedural fill in a mesh symbol must have the @StartRule specify @InMesh annotation, so it can be applied to multipatch geometry.
If you move a layer symbolized with mesh symbols into the 2D Layers category of a scene (or copy it into a map), the features will be redrawn with polygon symbols. Conversely, if you drag a multipatch layer from the 2D Layers category to the 3D Layers category of a scene, the features will draw with a mesh symbol. When a mesh symbol with a procedural fill symbol layer is moved into a 2D context, the procedural rule package will no longer be valid, because it references a rule package where the @StartRule specifies @InMesh annotation. Choose a rule package with a @StartRule that specifies @InPoly instead. Rule packages are created in Esri CityEngine.
Material fill symbol layers include a material mode to specify how the selected color is applied.
|Material mode type|
The RGB values of the object are multiplied by the RGB values of the selected color. This is generally the best choice when the object is white, or nearly white.
The hue and saturation components of the selected color replace those of the object. The value components of the selected color and the object color are multiplied together to obtain the final value component. This is generally the best choice when you want to overlay color to an already colored object.
The texture and color of the object are fully replaced by the selected color.
Mesh symbol basic properties
Mesh symbols have only one basic property, Color. This property is defined in the Format Symbol mode of the Symbology pane, on the Properties tab, on the Symbol tab . This is a shortcut to defining the color on the symbol layer. The color applies only when the symbol layer is color unlocked.
