Import 3D Files (3D Analyst)
Summary
Imports one or more 3D models into a multipatch feature class.
Usage
-
The 3D Studio Max (*.3ds), VRML and GeoVRML 2.0 (*.wrl), SketchUp 6.0 (*.skp), OpenFlight 15.8 (*.flt), COLLADA (*.dae), and billboards (PNG, JPEG, BMP, TIFF, GIF, and so on) formats are supported.
-
Preserve textured images in the 3D models by storing the output multipatch in a geodatabase. Shapefiles do not support the retention of textures.
-
If the top side of the resulting multipatch features are oriented sideways, try adjusting the orientation by using this tool again with the Y_Is_Up parameter enabled.
-
GeoVRML is the only format that has a defined coordinate system. Many 3D models are generated using local coordinate systems that center the XYZ axis on 0, 0, 0. Such features can be georeferenced to real-world coordinates using one of the following methods:
- If the 3D models need to be rotated and shifted, consider performing spatial adjustment techniques to position the features properly.
- If the 3D models are oriented properly for a given coordinate system and only need to be shifted to the correct position, consider customizing the Coordinate System properties to produce the necessary shift. If point features that define the position of each model's centroid in real-world coordinates are available, consider using the points as inputs for the tool to georeference the models.
-
Point and line geometries that may exist in a 3D file are not maintained in the output multipatch feature class, as multipatches do not support them.
Note:Unsupported geometry types for VRML files include Box, Cone, Cylinder, Extrusion, PointSet, Sphere, and Text.
Syntax
| Parameter | Explanation | Data Type |
in_files |
One or more 3D models or folders containing such files in the supported formats, which include 3D Studio Max (*.3ds), SketchUp (*.skp), VRML and GeoVRML (*.wrl), OpenFlight (*.flt), and COLLADA (*.dae). | File; Folder |
out_featureClass |
The multipatch that will be created from the input files. | Feature Class |
root_per_feature (Optional) |
Indicates whether to produce one feature per file or one feature for every root node in the file. This option only applies to VRML models.
| Boolean |
spatial_reference (Optional) |
The coordinate system of the input data. For the majority of formats, this is unknown. Only the GeoVRML format stores its coordinate system, and its default will be obtained from the first file in the list unless a spatial reference is specified here. | Spatial Reference |
y_is_up (Optional) |
Identifies the axis that defines the vertical orientation of the input files.
| Boolean |
file_suffix (Optional) |
The suffix of the files to import from an input folder. This parameter is required when a folder is specified as input. | String |
in_featureClass (Optional) |
The point features whose coordinates define the real-world position of the input files. Each input file will be matched to its corresponding point based on the file names stored in the Symbol Field. The Coordinate System parameter should be defined to match the spatial reference of the points. | Feature Class |
symbol_field (Optional) |
The field in the point features containing the name of the 3D file associated with each point. | Field |
Code Sample
The following sample demonstrates the use of this tool in the Python window:
import arcpy
from arcpy import env
arcpy.CheckOutExtension("3D")
env.workspace = "C:/data"
arcpy.Import3DFiles_3d("AddisSheraton.skp", "Test.gdb/AddisSheraton", False, "", False)
The following sample demonstrates the use of this tool in a stand-alone Python script:
'''*********************************************************************
Name: Model Shadows For GeoVRML Models
Description: Creates a model of the shadows cast by GeoVRML models
imported to a multipatch feature class for a range of dates
and times. A range of times from the start time and end
time can also be specified by setting the EnforceTimes
Boolean to True. This sample is designed to be used in a
script tool.
