I am using ArcGIS 10,3 and I am trying to create a python script that will automate a mapping process. I have point feature classes and polygon feature classes. I have used MakeFeatureLayer_management to create layers. I then use SelectLayerByLocation to select the polygon that INTERSECTS with the point layer and then I add both the point layer and polygon to the mxd. Once I have them there, I then zoomToSelectedFeatures. I am having trouble clearing the selected features once they have been added to the mxd prior to my exporting the mxd to a pdf. Any help would be appreciated.
