One Answer:
I'd probably use JOSM with the building plugin; should allow you to attach to nodes for the starting edge and drag out to the distance you want it for one side. Repeat or copy/mirror for the other side and then join it all together as a single object...depending how precise you wanted to be in maintaining the original points relative to the new object. answered 21 Apr '19, 01:07  mirror176 |
Thx for your proposal to use JOSM. I did it with help of the German site http://www.senotto.de/index.html?Tipps%20und%20Tricks This can do it for one side. The other side I mirror "by hand".
