I created a drawing in Inkscape 0.92.2 (in Windows 10 Pro 64 bit) that was built using hundreds of 1x1 rectangles which are snapped to each other. I've tried grouping and combining, but no matter what I do, the boundary lines between the rectangles are remain visible. https://i.imgur.com/pwAPoqr.png...

In this very crude drawing, http://i94.photobucket.com/albums/l100/graystrickland/Sheild%20with%20Lightning%20Bolt_zpsssciyni2.png the ends of the lightning bolt look blunt , not sharp. The lightning bolt is a path, 10 pixels wide, which is easier to see here: http://i94.photobucket.com/albums/l100/...
