Loading from pdb files using Pymol

Question

[kingkenshin1997]

" pymol.cmd.load('ftp://ftp.wwpdb.org/pub/pdb/data/structures/all/pdb/pdb'+pdbId+'.ent.gz') "

Every time i use the above command in succession ,the following pdb file gets loaded into the same state.. I want to know how can I clear the old state and work on it instead of creating a new state.?
