Is it easy for revit to make a building model of brick-concrete structure?

It's easy to do, but it depends on how carefully you do it. For example, it's just a lintel structural column or something. If you want to make a horse's teeth stubble, you need to modify the outline of the wall. I don't know your purpose, but if it's just a building, I suggest not to do it, and you can't see it after doing it. Because there is external wall decoration, you can still do it if you want to do construction simulation.
