Add 3D Formats To Multipatch (Data Management)

Summary

Converts a multipatch to a 3D object feature layer by linking the feature class with one or more 3D model formats.

Illustration

Usage

• This tool converts a multipatch feature class into a 3D object feature layer by creating additional tables associated with the multipatch.

• One or more 3D model formats can be associated with the multipatch to enable the lighting, reflectance, roughness, textures, materials and other visualization effects supported by those formats.

• The 3D object feature layer can be used without an associated 3D model. This will provide the texture optimization of the 3D object feature layer for the multipatch feature class. In a multipatch, the texture is stored for each feature independently, and the memory used for rendering the feature will require loading the geometry and the textures in one stream. The 3D object feature layer stores shared textures only once and can load the textures separately from the geometry, allowing the same data to be stored and processed more efficiently.

Parameters

Dialog

Label	Explanation	Data Type
Input Features	The input geodatabase multipatch feature that will be converted to a 3D object feature layer.	Table View
Use multipatch materials (Optional)	Note: This parameter is no longer supported. The option to control whether multipatch materials were used was removed to improve this tool's usability. Materials will always be used when they are available through the 3D object feature layer, and they will be automatically removed when the 3D object feature layer capabilities are removed from the multipatch. Additional parameters are available using the dedicated API for multipatches.	Boolean
3D Formats to Add (Optional)	Specifies the 3D formats that will be associated with the multipatch features. Each input feature will be duplicated for each selected format. The available options depend on the codecs installed on the computer. Collada (.dae)—The COLLADA format will be added. Autodesk Drawing (.dwg)—The DWG format will be added. Autodesk (.fbx)—The Autodesk FilmBox format will be added. Khronos Group glTF binary (.glb)—The binary Graphics Library Transmission format will be added. Khronos Group glTF json (.gltf)—The JSON Graphics Library Transmission format will be added. Industry Foundation Classes (.ifc)—The Industry Foundation Classes format will be added. Wavefront (.obj)—The Wavefront format will be added. Universal Scene Description (.usdc)— The Universal Scene Description format will be added. Compressed Universal Scene Description (.usdz)— The compressed version of the Universal Scene Description format will be added.	String
