'''Join areas that overlapping each other.'''

You can select two or more [wikitr:/Help/Concepts/Object#ClosedWays closed ways].
* If one way is surrounded by the other(s) a multipolygon will be created  automatically.
* The order of selection matters, as the remaining way will keep the [wikitr:/Help/Concepts/Object#ObjectId object id] and [wikitr:/Help/Concepts/Object#ObjectHistory object history] of the first selected way with positive id.
* All [wikitr:/Help/Concepts/Object#Tags1 tags] with only a single value and all relation memberships from all ways will be added and the [wikitr:/Help/Action/CombineWay#TagsMembershipsConflictDialog Tags/Memberships Conflict Dialog] will open if manual decisions are needed. In normal user mode it will additionally warn before adding any tag or membership the ways do not have in common, like Combine Ways, see [wikitr:/Help/Action/CombineWay#CombineConfirmation Combine Confirmation].
