FBX exported from Navisworks doesn't display in Unity

Questions & Answers

Hi community,

I have a BIM model of a large plant building in .nwd format. I used Navisworks to export it to FBX file. I tried to export the whole model (~1 GB large), then also tried exporting the model in parts (architectural, Plumbing, MEP, structural, etc… ) as seperate fbx files. I anyhow managed to import them (both the combined and the broken-down models) into unity with all materials and meshes intact.

However, the issue is that, I cannot see the model in Unity scene view at all, no mater how much I scale the model or do whatsoever possible to solve any visualization issues.

In the inspector, the model seems to be fine and even the meshes are imported and are all in place under the fbx file.
What possibly could be the issue that I cannot see the model in scene view?
Attached are a few screen shots to explain better what my problem is.

Thanks in advance :slight_smile:

My first thought was scaling issues - so if you havent allready, select your model in the scene view click ‘f’ for focus - if the model is WAY to big/small in scale, if will focus in on it, and you can see if it is really there or not.

Secondary, I would look at the import settings. Maybe something is up there (scaling here as an example - if you scale it in your program, and then unity scale it as well, you might see problems.) Also, there might be a chance that stuff like “Optimize mesh” and other settings is making “stuff” happen on such a big special model.

Third, I would try to just export a tiny bit of the model to see if that works. If there is something wrong with the exporting of the object, it easier to find out with small objects.
