Heya, thanks for your edits recently. :) Did you know that you can press the ‘Q’ key to automatically square the corners of buildings when you add them? It makes regular buildings easier to draw.

Please also note that you should align the aerial imagery with the OSMUK Cadastral Parcels overlay (in the ‘Background Settings’ panel on the right in the editor) before editing, to account for parallax errors in the imagery. The error can be 0-3m in both dimensions and varies from village to village, so it’s important to get the offset right.

Happy to answer any questions you might have about this :) Happy editing!
