So I have a multipatch feature class of 3D extruded buildings across a large area (~600,000 buildings), previously I would load these into ArcScene using an AOI to restrict it drawing every single feature. However this doesn't exist in Pro (which we are all being told to move to!), so how do I get a feature class like that to load into a scene? Does the visibility range have any noticeable effect on the load? It may restrict the draw (sometimes) but still seems to want to load every single feature into memory first!
