Examples include site addresses, water hydrants, and trees. You can create objects or data points that don't require lines or areas to store information or convey meaning.
Point features identify specific x,y,z coordinate locations on a map. To learn more, see Create multipatch or 3D Object features. You can import 3D models directly from your file system, create them from scratch by creating and extruding polygons using an additive workflow, or start with a basic predefined 3D shape and modify it until you create the feature you need. Feature templates that create Multipatch or 3D object features include several tools to create them in different ways. You can edit them with standard editing tools that modify vertices. Multipatch and 3D object features are intrinsically 3D features capable of levels of detail (LOD) ranging from a simple cube to complex 3D models. To learn more, see Create annotation features. You can also configure linked annotation to automatically add, delete, or move with the linked feature. For example, text strings for feature-linked annotation are linked to the value of a field or fields from the geographic feature to which it is linked.

You can link an annotation feature class to a geographic feature class and automate specific update behaviors. Examples include text that emphasizes the name of a country versus the name of a city or the name of a river. You can style them for a particular cartographic aesthetic. Generally, they are placed alongside labels in a planned visual hierarchy to communicate the importance of a particular feature. Annotation features are textual elements placed on a map to name or describe geographic features. Another project might require rivers as polylines to model water flow and also as polygons to calculate area coverage. You might, for example, need to use polygons to show city parks at display scales less than 1:100,000 and use point features for greater scales. 
In some scenarios, you may need to create more than one feature type for the same data. Feature types you can createĬhoosing which feature type to create depends on the objects or data points you intend to represent, the information you need to capture, and the type of analysis for which they will be used. If you have a 3D elevation surface on which your 2D features are located, you can use the Interpolate Shape tool to interpolate z-values from the elevation surface and convert them to 3D features. If 2D features contain dimensional attributes, forĮxample height values, you can convert them to 3D features using the Feature to 3D By Attribute. You can convert a 2D map view containing 2D and 3D features to a 3D scene.įor a basic workflow to convert a map to a scene, see Configure a scene for 3D editing. Scenes allow you to tilt your 2D map and edit data in three dimensions using a vertical axis. The referenced geometry of a feature can be stored in multiple formats, which supports many workflows that integrate 3D model files from other applications.įor visualization purposes, creating 3D features is commonly performed in 3D scenes.
A 3D object feature class stores and manages features in the geodatabase using a defined geographic location with a referenced 3D geometry mesh. In addition to storing 3D geometry, multipatch features can store color, transparency, and texture information. Multipatch features are 3D shell objects comprising 3D polygon faces. Line and polygon features store a z-value with each vertex. Point features store one z-value per feature. Z-aware point, line and polygon features are simple features that are configured to store z-values when the feature class is initially created in a geodatabase. There are three 3D geometry types from which to choose in ArcGIS Pro, each with their advantages and disadvantages: 3D featuresģD features store x, y, and z coordinates with their geometry. To learn more, see Extrude features to 3D symbology. To learn more, see Elevation surfaces.ĢD points, lines, and polygons can be extruded vertically to create 3D lines, walls, and building footprints, respectively. Although 2D features do not inherently store z-values, you can display them in 3D space by deriving z-values from an elevation surface or extruding them to appear three-dimensional.įeatures such as street vehicles and trees can naturally derive z-values from a ground surface without needing to convert them to 3D. 2D featuresĢD features store x and y coordinates with their geometry. The ability of a point, line or polygon feature to store z-values is configured when the feature class is initially created.įor a basic workflow to get started creating features, see Get started editing. The two-dimensional (2D) or three-dimensional (3D) features a feature template creates is determined by the data source for the layer or layers it references.
