What is a good way to get an extent object for the features returned by a da.SearchCursor with a where_clause applied? Certainly, I could apply a selection to the FeatureLayer and then use the getSelectedExtent method on the Layer object but frankly, I find SelectLayerByAttribute_management to be an expensive transaction. Add to this that I would also need to go back and clear the selection too. I just want to zoom to the extent of the returned features of the SearchCursor. Ideas?
with arcpy.da.SearchCursor(FeatureLayer, "SHAPE@", searchQuery) as rows: rowCount = 0 for row in rows: rowCount = rowCount + 1 print str(rowCount) if rowCount == 0: pythonaddins.MessageBox("No features found which meet criteria.", "ERROR: INVALID SEARCH CRITERIA", 0) return elif rowCount == 1: if row.type == "point": extent = row.extent df.extent = extent df.scale = 5000 arcpy.RefreshActiveView() del extent del rows else: print "Geometry is: " + str(row.type) return elif rowCount > 1: # so...now I have a bunch of features/rows returned..hmm # how to go about getting the full extent for these # returned features without applying a selection
