3D Label Map Manager allows you to manage all 3D thematic map layers in the scene and change the 3D thematic map settings for favorable effects. Select a 3D label map layer in the Layer Manager and click the group dialog box launcher for the Label group to display the 3D Label Map Manager. You can save a thematic map you have created as a template for reuse. Please refer to Save to Thematic Map Template Library. Set the transparency of the labels in the 3D label map.
