[Qgis-user] ugly results with new symbology: how to improve them?

[Mayeul Kauffmann]

Hi Paolo,
 I would just make everything round (cap and join) but then maybe
problem with the offset.
Then, if not enough:
You can solve this by taking a simple yellow line instead of two:
You need:
-one very wide gray band (below)
-one slightly smaller yellow band (above it)
-one slightly smaller grey band
-the dashed white band (on the top)

You also need symbol levels ON on because you have several roads.

Your qml looks almost perfect by me (see attachment), so if the above s
does not work, I can help more but need a sample file (your scale is
strange: "30 000 gradi"???)

Hope it helps,
Mayeul
