I used to use the SA toolbar to do my feature to raster conversions but I don't see that available on the toolbar in v10. I've set the environment settings that I need. The resulting raster will not stay within my analysis mask or processing extent. It does snap to my snap raster (all the same GRID: "cnty_bndy") and output the correct cell size. I don't understand why it creates cells for features that extent beyond my analysis mask? I've tried polyline to raster and feature to raster. This isn't very complicated I know.
(There is not an orange cell underneath the darker cell).
