I have covered using FBX to access Navisworks data for downstream use. What about KMZ? This format contains lightweight geometry as well as some model structure. It is actually quite difficult to find an easy way to go from KMZ to IFC, or KML to IFC. But, it can be done!

Here’s one method:

  1. Export desired view from Navisworks to KML with “collapse” set to None. This will bring the full model hierarchy with the KML file (see help for more info)
  2. Install ArchiCAD 16 and the Google Earth import / export plugin
  3. File Special – Merge, select the KMZ (this part could take a while)
  4. File Special – IFC 2×3 – Merge to IFC Model…
  5. Select an IFC file (maybe make an empty one to merge with first, like this one)
  6. You will get geometry and some basic data, but the main thing is that the object segregation is still present
  7. From here you can import the IFC file to Revit as usual

Note: you can use 7-zip to extract a KMZ and you will see the KML file inside.

How to use

  1. Download and install the latest, free Google Earth applicationExternal link icon. Existing Google Earth users should ensure they have updated to the latest version (version 7.0.2 or newer).
  2. Save the qldglobe.kml file to your computer and double click on the file.

Some notes:
The default imagery used in Queensland Globe is the best available to the Queensland Government that can be released for public viewing.

All layers have been pre-set to only display between certain scales, i.e. more detailed layers will only display at larger scales (you may need to zoom in to see them).
