[GIS] QGIS individual symbol rotation

labelingqgisqgis-2.14symbology

I've digitised some symbols in QGIS (2.14.1) as a new Shapefile point layer. I want the symbols to be rotated to different angles.

I've worked out that I can have a data defined rotation field in my attribute table and I've put this in and it seems to be working. However I can't workout if there is a way to rotate the symbol in the map window and have that update in the attribute table: so I'm stuck with putting values into my attribute table manually.

I know how I can rotate label with the Label Toolbar so I really hope that there is a similar function for symbol rotation.

In QGIS 2.18+ (and QGIS 3) this is a built in feature.

Create the layer as before:

With a rotation column that has 0 to begin with. Make sure to set up the data defined override for the symbology. In my case I did it for both the square and the question mark that made up my symbology.

Then using the "Rotate Point Symbols" tool from the advanced digitizing toolbar. You can rotate the point.
