this doesn’t work. I get just the name of the master-block
import rhinoscriptsyntax as rs
block_uuid = rs.GetObjects("Select Block(s): ",rs.filter.instance)
for block_id in block_uuid:
block_name = rs.ObjectName(block_id)
sub_blocks_ids = rs.BlockObjects(block_name)
#print sub_blocks_ids
for sub_block_id in sub_blocks_ids:
sub_block_name = rs.ObjectName(sub_block_id)
print sub_block_name
if sub_block_name is None:
break
