![]() ![]() To add a part to an existing feature, use the Continue Feature tool to digitize the new part.To create multipart features from existing polygons by aggregating them based on attributes, you can use the Editor > Merge command (produces multipart polygons when the selected polygons are not contiguous) or the Dissolve geoprocessing tool, and specify that the output have multipart polygons.(A shortcut to the Finish Part command is to hold down the SHIFT key and click.) Draw the sketch of the next part, and finish the sketch when you are done creating all the parts. To create a new multipart feature, create a sketch of the first part, right-click, then click Finish Part.Here are some of the common tasks performed when working with multipart features: You can create, edit, and work with multipart features using editing tools as well as geoprocessing tools. For example, the individual islands that make up Hawaii are often represented as a multipart polygon feature. The buildings are now extruded to the correct height but are not yet aligned with the surface.Multipart features are composed of more than one physical part that only references one set of attributes. Click the Unit drop-down menu and click Feet to match the projection of the data. Subtract the Adjusted Surface Elevation from the Roof Elevation,. Click Feature extrusion type and click Base Height. Click the Buildings layer in the Contents pane and click the Appearance contextual tab. Click OK to close the Properties dialog box. Starting the buildings at a height of zero will ensure the buildings are extruded to the correct height and will not be affected by the slope of the terrain. The buildings are now at a height of zero, drawing below the terrain surface. On the Elevation tab, click the Features are drop-down menu and click On the Ground. Right-click the Buildings layer and click Properties. In the table of contents, drag the Buildings layer from the 2D Layers group into the 3D Layers group so we can extrude these buildings and visualize them in 3D. Add the building footprints to the scene in Pro using Add Data on the Map tab. The base layers for our scene have been completed so let’s begin working on the operational layers for this web scene. Right click on Ground under Elevation Sources and click Add Elevation Source to add the DTM to the scene.Ĭreating 3D Buildings – Multipatch Features Next the elevation data needs to be added to the scene. To add the layers provided click on Add Data in the Map tab and select the Portland_Topo raster in the file geodatabase. In my default scene I removed the World Topographic and World Elevation layer. To remove the layers from the scene right click on them and select remove layer. Remove the default layers from the scene because these layers are cached and are in a different spatial reference from the layers about to be added and lightweight clients like Scene Viewer cannot reproject cached layers. When opening ArcGIS Pro, create a new project and select Local Scene from the Project Templates and give your new project a name.
