[Qgis-user] polygon segment

2013-07-09 Thread Jake Maier
I want to create a new polygon and in one area it should follow the segments of another polygon . (I have a forest and want to delineate the stands.) Which plug-in can I use to tell the program that from here to there it should just follow an existing polygon either in the same shapefile (stands)

Dear Jake, you can use the topological editing. In Settings/Snap options dialog enable topological editing, check Avoid Intersections for the editing layer and optionally set a tolerance for snapping. After it you have to draw only the missing part of the a new polygons. Regards, Zoltan On
