Hi!
I have a 3D city model made out of individual polygons. Polygons forming one building have a common ID (also attr like Type: Wall, Roof). I need to combine/merge/aggregate together shapes beloning to each building, so when I select a building it markes an entire entity and not just one of the polygons. The output should be a shapefile or multipatch.
I tried using dissolve but it fails each time. I want to use data later in Pro and CityEngine.
Anyone has an idea how to do that kind of ID-based multipart to singlepart merge?
I attached also sample data
Thanks!
