Candice DelamarreThe screenshot of an interior view of your merged model from BIM 360 Model Coordination showing the plumbing elements. You’ll probably need to select and hide the Partition element from the architectural model to see your plumbing fixtures.

I struggled with mirroring because the two systems are not exactly mirrored, so I had to extend the hot pipe to the lavatories. Apparently, the risers in the Northern restrooms conflict with my Structural model, but not the ones in the South restrooms.

I think there might be a problem with the horizontal alignment (levels were copied-monitored so are fine) of my 2 models, but I don't really understand why.
