Drawn by hand in Inkscape, I have several polylines and polygons, more ore less in contact.
I want to build a polygon from them (in zone A) and fill it with a given colour. The desired polygon will have as border the small polyline on the right and a portion of the longer polyline on the left (that belongs to polygon B). It is a cartography issue.
I tried several techniques but I am lost in the Inkscape menus. Thanks for helping me
