If the 3D Piple Line is located underground, when loading the 3D Network Dataset into the 3D Scene, its height mode needs to be set to Absolute Underground Model through the attribute. Open underground mode and set the transparency. The specific operation steps are as follows:

1. Select the built 3D Network Dataset, and select Add to New Spherical Scene "in the Context Menu.
2. In Layer Manager, individually select the pipeline and pipepoint layers for the 3D Network Dataset, and in the Style Settings "tab, set the layer Height Mode to Absolute, and if the data is from underground, set Data From to Underground.
3. In the Underground group in the Scene tab, set Underground Mode to On and set Transparency to 50%.

Precautions

The height mode and data source of pipeline and pipe point Layer Settings should be consistent, otherwise the pipeline and pipe point will not be displayed correctly because of the inconsistent elevation.
