I need to Purge the layer not used that dont contain nothing.
There is a flag that contain this information.
Or i must ,before erase the layer, make a selection with filter for each
layer?
to Purge block i have found :
ObjectIDs = Blocco.GetBlockReferenceIds(True, True)
this function return a collection of objectid that is the number of
blockreference still insert.
Many thank's in advance.
