Hi everybody!
I've got ONE file geodatabase with about 400 feature classes (FC). Here attached is a part of that .gdb.
I need to merge that features (or better append one feature - 00 - to the other)  that has got the same name except for the "00".
For example:
"_01P11_line" must be merged with "_01P11_line00"
or better
"_01P11_line00" (input) appended to "_01P11_line" (target)
and, after the merging/appending, delete the "00" feature class.
I was thinking to proceed with an iteration in modelbuilder or/and a python script...
could someone help me, please?
Thanks in advance
