Ah thanks, got it now. Any idea how I can write the output layers out with e.g. <feature_name>_roads.shp <feature_name>_buildings.shp (I’m basically trying to iteratively loop through wards, clipping out all the roads and buildings for each ward to a file named on the ward name). Also being able to put the date into the name would be great.
