I'm a new user of Inkscape and I have a little problem. I would like to join some adjacent polygons without border between them. I select my polygons, I do a Ctrl+G", they are well joined, but it remains borders between former independent polygons. It makes some problems when I fill my joined polygon in red and borders in black for example (borders inside polygons are till visible). Does exist a solution to avoid this problem ??
Sorry for my bad English, it's not my mother tongue
