R24/25 Best Practices for Large Detailed Terrain - Toposolids

Hello Everyone!

What are the best workflows for working with excessively large Toposolids? Area is 3,421,944 Sqft

Currently a student, modeling a large campus topography where slope plays a major role from building to building, 100ft has a drop of 10ft nearly. 

Now, I understand it is ridiculous, but we wanted to see how much we could accomplish in a Revit file.. 

Workflow: Topo in Rhino 7 from GIS data, make contours & export to CAD, CAD contours linked to Revit, make Toposolid from Import, clean up & edit terrain as it needs adjusted for our proposal. This is all experimental

Issue: Points take over a minute to edit each time the topo is adjusted in any manner -if it doesn't crash. Note: Working the topo in an empty, separate file before copy/pasting was much easier

Some things I have seen online so far:

- Breaking up area into multiple toposolids within the same file (What is a good workflow for this?)

- Linking the topo in (wholistic or as multiple topo files) (Also what does that look like?)

- Don't -use a different software & link that file in...

Aside from all of that, does anyone know how to edit the "sketch" of a toposolid where you could cut out a section on the interior -so that the edge conditions of the interior cut assume the heights that they were previously, as opposed to dropping or raising to some other height? I assume that "default" height is in a setting somewhere but I have missed it

Thanks for anything!
