附加信息

As per the documentation from https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/extrude-features-to-3d-symbology.htm, using the Base Height extrusion type, extrusion is added to each vertex of each feature's base height. A z-value is calculated for each vertex of the feature's base and each feature is extruded to those z-values. In the case of polygon features, top and base faces are created to connect to the extruded walls to construct a closed shape. When Vertical Exaggeration is set to 1.00, the ground elevation is used as the z-value for each of the vertices of the building. Since the actual ground surface are not 100 percent flat, this results in the closed shape to not being flat. The artifacts are the result of triangulating a non-flat polygon on the top and bottom of the extrusion. If the desired result is a flat shape, then ensure to use the "At an Absolute value" elevation mode for the features before extruding then.

解决办法

If the desired result is a flat shape, ensure to use the "At an Absolute value" elevation mode for the features before extruding them, or use one of the other extrusion modes.
