I have a layer with like 20 polygons which I imported from Google Earth Pro. Is there a tool which will transform only one specific polygon from all those in a same layer into lines (Vectors)?






polygon vector qgis-3.2 qgis-3.4

  • Yeah it is same but problem is that when i imported from GE there are a lot polygons on same layer so I have one which is really big and over whole map and I am not able to shut it down, so that is why i was thinking changing it to line, but not whole layer just that one specific one.

  • Do you simply want to be able to see what is underneath? Then change the style of that layer. Do you want to remove that polygon from the layer? Then mark it, use save as to export the marked polygon to a new file and then delete it from the old layer.

            One-line joke

            A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
