I’m currently working on a site model and would like to keep as much of the workflow as possible inside the Grasshopper pipeline. I know I can use Revit’s native excavation tool and then reimport the modified geometry, but I’d like to avoid that step if possible.
That is was I was asking for. I don’t have any experience with RevitAPI or any coding. I can looking into what it would take to add this as a c# component myself if needed.
