I can't find the example model "contours from points" in QGIS 2.6. Is there another tool for creating contours from points, besides the QGIS Contour plugin?
there is a contour-plugin, which you can load via plugin-manager. additional infos here: https://github.com/ccrook/QGIS-Contour-Plugin
You're talking about the Contour Lines From Points model. I still have 2.4, I saved it for you as a .model
