![]() ![]() ![]() In addition, multipatch features can be constructed programmatically using ArcObjects. The Import 3D Files geoprocessing tool will do the same but provides more import format options such as VRML. The Layer 3D To Feature Class geoprocessing tool will convert points symbolized by a variety of model formats (such as SketchUp, OpenFlight, 3ds, or COLLADA) to a multipatch feature class. Multipatch features can be created by importing existing 3D models into ArcGIS using geoprocessing tools. This assumption can be problematic, particularly if x,y units are geographic (latitude-longitude). If no units are defined, ArcGIS will assume that the z-units match the x,y units. Reply 3 Kudos An Unexpected Error has occurred. Then use the Layer 3d to feature class to create a multipatch. ![]() The units and datum for a feature class's z-values should be defined on the containing feature dataset (if one exists) or on the feature class itself (if there is no feature dataset). extruded feature class multipatch Reply 0 Kudos All Posts Previous Topic Next Topic 1 Reply by NeilAyres 09-17-2019 03:51 AM Create a layer file in Scene with the extrusion set. Both methods are fully supported in the display and analysis of the resulting 3D feature class. The values can represent absolute heights or relative-to-ground heights. Z-values are used for representing the shape and elevation of your multipatch features. Learn more about converting 2D features to 3D features What do the z-values represent? ![]() Learn more about creating new 3D feature classes To create a new multipatch feature class, simply choose Multipatch Features from the Type drop-down menu when defining the feature class's geometry. How do I create a multipatch feature class? You can use the Is Closed geoprocessing tool to verify that a multipatch is properly closed.Įxamples of multipatch features include textured buildings, lamp posts, trees, subsurface geologic formations, underground structures, or certain types of analytic surfaces. Input the corresponding Feature layer to be converted into a Multipatch, put it in a familiar directory for output. The patches must not intersect each other, and there must be no gaps or empty spaces in the shell. Convert to feature class In ArcToolbox > 3D Analyst Tools > Conversion > Layer 3D to Feature Class is the tool we will use to convert the extruded features to a ‘Multipatch’ feature class. The patches it is composed of must all have the same counterclockwise orientation of their coordinates and participate in defining the shell of the volume. The feature must represent one distinct volume. For a multipatch to be considered closed, it must be constructed in the correct fashion. Closed multipatches may be used in additional analysis tools, such as Union 3D and Intersect 3D. Some multipatch features are considered closed, meaning they properly define a volume. While it is possible to model the base z-value of a multipatch using a numeric feature attribute, this option may not support all the same analysis and interaction options that are available when using embedded z-values. Likewise, if one of the TIN surfaces has a coincident boundary with the other in the region overlapping with the polygon, consider modifying the TIN's data area either through interactive editing or by using the TIN Domain tool to output the TIN's footprint as a polygon, applying a slight buffer to the polygon, and loading the polygon back into the TIN using the Edit TIN tool.All multipatches store z-values as part of the coordinates used to construct patches. If the input polygon shares coincident borders with any of the TIN surfaces, consider using the Buffer tool to slightly modify the polygon's shape. The tool may fail to generate a valid ouput if any of the input datasets have coincident boundaries with another input dataset.
