3/12/2023 0 Comments Esri multipatch geometry type![]() In the image below you can see how 2D features (Crème color) are dependent on a surface for display in a 3D scene, whereas 3D features (Red color) have z information and are located in the elevation they belong to without extrusion. They already have Z information in their geometry. 3D features can be displayed without the need to draping them over a surface like DEM. This document demonstrates how you can create the multipatch geometry via ArcObjects. For now the only supported type of features for. The image below shows the multipatch icon. For many 3D spatial Analysis, you need 3D features or Multipatch features.ģD features are features with 3D geometry. The multipatch geometry type, a geographic information system (GIS) industry standard developed by ESRI in 1997, is used to define the exterior shell representation for 3D objects. Supported geometry types CGA example for a rule that expects polygon geometry as input:-Lot is the start rule. Also, the icon next to a multipatch feature is a 3D feature. It is just a 3D visualization of your 2D data. Having an extruded building, does not make your features with 3D geometry. It means that you extruded a 2D polygon based on a ‘Z’ attribute you extracted from LiDAR Data or DSM or any other sources. Note: What you have created in Lesson 5 as a 3D building, is an extrusion from attribute. Make sure the following layers are checked in the 3D Layers Content Pane: Up_Roof_Segments, Building_Footprints., and Topography. In the Projects Folder (C:\Users\YOURUSER\Documents\ArcGIS\Projects\ UniversityParkCampus), Save Project as UniversityParkCampus_Lesson6_Shadow. difference: The geometry types are different, one is Multipatch type and the other is 3D Object type the display is different, 3D Object can express advanced.
