Exporting a 3D Model from SketchUp

Updated by Corine Barbazanges


Before exporting a 3D model from SketchUp for use in SENAR WalkIn, please ensure the following points:

  • Ensure your model is built to the correct scale.
  • Place your object at the origin (0.0.) coordinate system in the scene.
  • Ensure the base of your model (e.g., the floor of the house) aligns with ground level. Do not place the model on a raised platform.
  • Locate the pivot point at the center of the model.
  • Convert TGA textures to PNG.
  • Ensure that texture paths are relative.


To export your SketchUp model:

  • Go to the "File" menu and select "Export" > "3D Model".
  • Choose the OBJ or FBX file type.
  • Select "Options" from the drop-down list.

In the Export options: 

  • Check "Export only current selection" if you've made a selection before beginning the export process. If you leave this option unchecked, the entire model will be exported.
  • Check "Export texture maps" to export textures applied to faces with your OBJ file.
  • Check "Swap YZ coordinates (Y is up)"
  • In the Units dropdown:
    • If you are exporting as an OBJ, choose "Meters
    • If you are exporting as an FBX, opt for "Centimeters"


After exporting your model and textures, prepare your file for upload as follows:

OBJ:  Create a ZIP that should contain, at the root level:

  • A single OBJ file
  • The .mtl file
  • A folder containing the textures.

FBX: You can create either a textured FBX or a ZIP file. The latter should contain, at the root level:

  • A single FBX file
  • A folder containing the textures.

Finally, upload your file to SENAR WalkIn.
