Select which tool to use to import 3D features in ArcGIS Pro “Import 3D Object" or "Import 3D File”

Summary

When bringing 3D models into ArcGIS Pro (such as buildings, vehicles, or outdoor equipment), you have two main tools to choose from: Import 3D Files and Import 3D Objects.

While both tools turn external 3D files into map features, they are designed for different file types, license levels, and quality needs. Think of Import 3D Files as the traditional tool for basic or older 3D files and Import 3D Objects as the modern tool designed for realistic, high-quality 3D graphics and building designs.

Quick Comparison

Detailed Tool Breakdown:

1. Import 3D Files

Use this tool if you are working with standard or older 3D design files.

• Best For: Simple 3D shapes or older simulation files (.3ds, .wrl, .flt).
• How it places models: If you have a layer of point locations on your map with matching file names, this tool can place hundreds of 3D models onto those points all at once.
• Note: The centroid of the model is placed in the point.
• Key Requirement: You must have an active 3D Analyst Extension license to run it.

2. Import 3D Objects

Use this tool if you are working with modern 3D graphics, CAD drawings, or detailed architectural models (BIM).

• Best For: Realistic 3D models (.glb, .gltf), CAD/BIM building models (.dwg, .ifc), or detailed graphics (.fbx, .usdz).
• Visual Quality: Supports modern material lighting and reflections (looks much more realistic on screen).
• Key Requirement: Does not need the 3D Analyst extension, but requires an ArcGIS Pro Standard or Advanced license.

Helpful Tips Before You Start

1. Avoid the Windows "3D Objects" Folder: If your 3D files are saved in your Windows default user folder (C:\Users\YourName\3D Objects), the Import 3D Objects tool won't be able to open them. Move your files to a simple folder like C:\GIS_Data first.
2. Fixing "Sideways" Models: The tip mentions checking "Y Is Up" for models lying on their side. In ArcGIS Pro, the "Y is up if unspecified by data" parameter specifically applies to Wavefront Object (.obj) files rather than all 3D formats. Specifying this avoids confusion when importing non-OBJ formats like .fbx or .gltf.
3. Keep Your Textures Intact: Always save your output layers into a File Geodatabase (.gdb). Saving 3D outputs as old shapefiles will lose all colors and textures as shapefiles do not support 3D object geometry classes or complex texture materials.

Procedure

• Choose 'Import 3D Objects' if:
• You have modern files like .gltf, .glb, .fbx, .ifc, or .dwg.
• You want your 3D models to look realistic with high-quality textures.
• You don't have the 3D Analyst extension.
• Choose 'Import 3D Files' if:
• You are using older file formats like .3ds or .flt.
• You have a layer of map points that tell each 3D file exactly where to go.
