I can get QGIS to do what you need: http://img6.imagebanana.com/img/uewfzlmc/Workspace1_155.png
Selected the Symbol:Fill tree item and then selected Advanced->Symbol Levels Just enable symbols levels and it will render how you need. - Nathan On Fri, Sep 28, 2012 at 2:35 PM, Denis Rykov <[email protected]> wrote: > QGIS is used rendering order of symbol layers within features not within > layer.
