Path Of Travel Obstacles

[john]

Revit 2020 path of travel doesn't see obstacles in linked models. 

Is there a setting to enable this?

[barthbradley]

I don't see obstacles. I see opportunities.  😉 

It should work.  Have you checked your Route Analysis Settings?  

[john]

Yes. I have checked the settings.

Zone is set to 3000mm above view level and top at 5000mm above view level, as the zone is in ceiling space.

The zone is riddled with ducting, but "reveal obstacles" doesn't show obstacles in the linked model.

Post the two files (Link and Parent).

Thanks for your interest.

Unfortunately, I am unable to share as the project is a pharmaceutical production facility and is confidential.

The two files are also large, 1.6GB in total, the larger file of the two being the mechanical model which is linked into our architectural model. The project size is approx. 22 000m².

Is there any other way that you can assist?
