You are sharing a web scene or web scene layer that has extruded features. Extrusion is not supported and features will be flattened.
- Do nothing. The features will be flattened and your web scene or web scene layer will be shared.
- Convert the layer to multipatch features using the ArcGIS 3D Analyst tool Layer 3D To Feature Class.
Some 3D display properties, such as extrusion, are not supported when sharing a web scene or web scene layer. To avoid flattened features, convert your 3D display properties to multipatch features.
