3D Model Dissapears when zooming in

[RichardVincent1]

I have a 3D Model - loaded in ARCGIS Pro created from Drone Data ( as a I3S format) When I zoom in to view the details the dataset appears to disappear ( depth of field issue ? or a volume cube issue?) - Is there a setting to be able to zoom in to full resolution detail ?

Some things that may be occurring....

It might be automatic view clipping which you can try changing to manual https://pro.arcgis.com/en/pro-app/latest/help/mapping/properties/adjust-view-clipping-in-scenes.htm 

Another option is maybe the mesh is conflicting with the ground elevation source layer so you can uncheck that in the Contents pane to see if that's the problem.

thanks,
