I am seeking a way, using QGIS, to automatically add polygon features identical to others on the layer. In this case, they are water valves on a water network. Anyone know of a user-friendly way to add new valves that visually line up with the pipes without needing to manually draw the polygons through editor mode?

Is this a spatial task? From your question and the comment below it sounds like a drawing job.– SimbamanguFeb 15, 2014 at 13:09

It's a drawing job with a programmatic approach.– user25976Feb 18, 2014 at 1:42

You can simply start an edit session on the layer, select the feature that you want to re-use and on the Edit menu select Copy then Paste. This will put an identical feature on top of the selected feature which you may drag and move.

This is our current solution, but ideally we would be able to automatically rotate the valve to line up with the pipe. Feb 14, 2014 at 22:07

This technique also copies the attribute data. Ideally, creating the new feature would incite a custom form. Feb 15, 2014 at 0:00
