| | 7 | This tool quickly updates a [[JOSMImage(data/multipolygon)]] [wikitr:/Help/Concepts/Object#typemultipolygon multipolygon], one of the most common [[JOSMImage(data/relation)]] [wikitr:/Help/Concepts/Object#Relations relations]. |
| | 8 | |
| | 9 | The actual outcome of the action relies on the [wikitr:/Help/Dialog/SelectionList selected] [[JOSMImage(data/way)]] [wikitr:/Help/Concepts/Object#Ways ways] and relations: |
| | 10 | * If only ways without [wikitr:/Help/Concepts/Object#Membership membership] of a multipolygon are selected, the action is identical to [[JOSMImage(multipoly_create,24,link=,middle)]] [wikitr:/Help/Action/CreateMultipolygon Create Multipolygon]. |
| | 11 | * If one selected way is member of a multipolygon or, additionally to ways, a multipolygon relation is selected, the existing relation is updated by moving most of the tags from the ways to the relation and adding the remaining ways with appropriate [wikitr:/Help/Concepts/Object#Roles roles]: `outer` and `inner`. |
| | 12 | * If a way has identical tags as the relation, this will be assumed to be an [https://wiki.openstreetmap.org/wiki/Old_style_multipolygons old style multipolygon] and the tags will be removed from the way, regardless of whether it is role `outer` or `inner`. |
