What attributes must files have to use the 3D GeoViewer?

Xander den Duijn

FME Certified Professional

The following file formats are supported in the 3D GeoViewer:

  • IFC (Industry Foundation Classes)
  • FBX (Filmbox)
  • SKP (SketchUp)

A maximum size of 100 MB applies to each file format.

The requirements also differ per file format:


  • The file must be provided with a geo location through a coordinate system. The "Site" must also have the "RefElevation" attribute with a value. This value is used to inform the BIM model.
  • The unit of length must be millimeter, centimeter or meter (and not inch).


  • The file must be provided with a geo location through a coordinate system. This geo location applies only to the XY positioning.
  • The 3D model must be adjusted by height. This can be done in SketchUp Pro by adding a terrain and then placing the model on the terrain
  • To make textures on the building look good, we recommend that you make it "unique." You can do this in SketchUp by right-clicking on "Make Unique Texture."


  • It is not possible to specify a coordinate system for FBX files. For this reason, it is important that the 3D model is described by means of RD coordinates (Dutch Rijks Driehoek measurement X, Y in meters). The length unit used must therefore be meter.
  • The height at which the 3D model is placed must conform to NAP.
