Usage Feature layers with symbology that has the following properties will be exported to a multipatch: Extrusion or base height settings. It makes sense to use this function to group a collection of 3D polygon faces into a single multipatch polyhedron. Summary Exports feature layers with 3D display properties to 3D lines or multipatch features. In this case, what is the advantage of the conversion? If grouping by ObjectID then you will have the same number of entities - i.e one multipatch for each polygon. You can check whether the geometry is MULTIPATCH or POLYGON on the Feature Layer Properties -> Source -> Geometry. You report that your "output had the same amount of entities only they all were having the same geometry." It lists several other caveats why the conversion might not work. They have no fixed orientation that can be used for exporting. The position of these 2D symbols areĭynamically oriented to face the camera position in a 3D scene, so The Layer 3D To Feature Class docs for ArcGIS Pro state "[Marker One clue is that you are converting billboards. Without more information, we cannot be sure why it failed in this case. In the case of polygon features, top and base faces are created to connect to the extruded walls to construct a closed shape.Įach feature is extruded to the specified z-value from a field or expression as a flat top, regardless of the z-values of each feature.There are many reasons why 'Layer 3D To Feature Class'will fail. A z-value is calculated for each vertex of the feature's base and each feature is extruded to those z-values. The multipatch can be visualized in 3D using ArcScene or ArcGlobe. Only points, lines, and polygons support extrusion. The features can be created as 2D polygons or extruded multipatch features that provide a 3D bounding box whose z-values at the base and top reflect the range of elevation values found in the file. For example, you can extrude building polygons by a height value to create three-dimensional building shapes. This option is not available for point features.Īdd extrusion to each vertex of each feature's base height. Layer 3D to Feature Class is the tool we will use to convert the extruded features to a Multipatch feature class. Extrusion is the process of stretching a flat, 2D shape vertically to create a 3D object in a scene. They are extruded to a flat top at that value. A z-value is calculated by adding the extrusion height to the maximum z-value of each feature. This option is not available for point features.Īdd extrusion to each feature's maximum height. A z-value is calculated by adding the extrusion height to the minimum z-value of each feature. This is the default.Īdd extrusion to each feature's minimum height. Choose a feature extrusion type.įeatures are not extruded. On the layer's contextual tab (for example, the Feature Layer tab), in the Extrusion group, click the Type drop-down arrow.
