■ Adding 2D Rasters (page 443)
■ Adding an Image from a WMS (Web Map Service) (page 445)
To make a raster image transparent
1 Add the raster (page 437) to AutoCAD Map 3D.
You can use any type of raster, including a WMS image. The image does
not need to be transparent or have an opacity setting already.
2 Right-click the layer containing the image and choose Save Layer.
Save the layer to a .layer file.
3 Open the resulting .layer file in a text editor, such as Notepad, and find
the <FeatureName> entry.
4 Just under the <FeatureName> entry, add the opacity setting, using the
following syntax:
<Opacity>0.6</Opacity>
An opacity setting of 1 makes the layer completely opaque. A setting of
.1 makes it virtually transparent.
5 Save the .layer file.
6 In AutoCAD Map 3D, switch the Task Pane to
Display Manager (page 2060)
and remove the original raster layer.
7 Add any other entities to your map that will appear on layers beneath
the translucent image, and theme or style those layers.
8 Click Data ➤ Load Layer and select the .layer file you edited.
The translucent raster image overlays the opaque layers, and they appear
beneath it.
