Re: [Qgis-user] Convert Lines to Polygons
Hi, You could create a polygon from the layer extent. Then use a spatial query to get the attributes from your current polylines.

Well - Crap. Heh. There may be other suggestions coming! Good Luck, We're all counting on you!

First thought - take a look at the processing toolbox. Open it and search for Lines to Polygons and try that tool. It should convert your lines to polygons. The kicker is I don't *think* that will preserve attributes. So - you're halfway there *maybe*.
