Hi, I'm mapping a hospital close to me with quite a complex Shape. I've mapped all the different parts of it with building:part=yes and put it into a relation with the role=part. This relation (a) is of type=building. See: Relation a Then I created a second relation (b) with the outline of all the parts but gave it the role=outer. Additionally I created a line that represents the hole of that building and gave it the role=inner. Here: Relation b Eventually relation b becomes a part of relation a with the role=outline. But it does not seem to work 100%. What am I missing here? I don't wanna mess around any more and thought I'd just ask. Google didn't rely help or I haven't found my exact problem. (see my related post on reddit) Thank you. asked 18 Jun '21, 09:02  som-tam |
One Answer:
When a building is mapped with a multipolygon, the tags for the building as a whole go only onto the multipolygon relation, not on the outer way. So you should remove the answered 18 Jun '21, 10:53  Tordanik |
That's it. Thank you.
Also no need to use relations to map building parts, you can just rely on the geometrical relationships
