Hi all,

For the JOSM users:


I tend to use the X tool, but both ways illustrated are great.

The only part of the text that does not make sense to me is where it 
says in the "area intersections" method: "then select 2 nodes of that box"

My understanding and usage of the building tool is that if you select a 
building as a way, you know, just click on the building to select it, 
then switch to the building tool 'B', every building you draw will be 
parallel to that selected building. That is what it looks like he does 
in the animated gif demonstration.

If someone knows what the 'select 2 nodes' applies to and how it is 
different than just selecting the whole building, I'd love to hear it.

Thank you for the tutorial Andrey.

Happy building mapping!
