Well, I think found it.
Don't perfect but its works

import c4d
import os
from os.path import join, normpath
from c4d import documents

def export():

    dirpath = "c:/usr/temp/"  # temp directory
    global tdoc
    
    sobj = doc.GetActiveObjects(0)
    # isolate objects
    tdoc = c4d.documents.IsolateObjects(doc, sobj)
   
    # get path with object name
    full_dirpath = normpath(join(dirpath + (doc.GetActiveObjects(0)[0]).GetName() + ".obj"))
   
    # export to obj
    documents.SaveDocument(tdoc,full_dirpath,c4d.SAVEDOCUMENTFLAGS_0,1030178)        

if __name__=='__main__':
    export()

    documents.KillDocument(tdoc)

Hi @m_adam, thanks for you correction and advice, it's really usefull for me. I'm learn python just couple month and not sure in my code yet.

• yeah i'm missed this mistake
  full_dirpath = normpath(join(dirpath, (doc.GetActiveObjects(0)[0]).GetName() + ".obj"))

Thanks one more time, always good to have help and support!

@mikeudin Thanks, but don't undestand how works this command, i was tried to get list from isolated = c4d.documents.IsolateObjects(doc, selected) but it's give me nothing and i can't use for for it.
How do i can exported only selected list to obj, without dialog windows?

Sorry this is my first script for c4d, i'm maya user and little confused. Thanks

Whos knows any solution for it?

Hello guys,

I wrote small script and got one problem. I can't export selected objects to separate files, after export operation i got obj files with duplicate meshes inside. Which the command do i must use for it?

import c4d
import os
from os.path import join, normpath

dirpath = "c:/usr/temp/mayablender/"

def main():
    doc = c4d.documents.GetActiveDocument()
    selected = doc.GetActiveObjects(0)

 
    for ob in selected:
        ob.DelBit(c4d.BIT_ACTIVE) 
        doc.SetActiveObject(ob)        
                   
        
        full_dirpath = normpath(join(dirpath + ob.GetName() + ".obj"))

        # export to obj
        c4d.documents.SaveDocument(doc,full_dirpath,c4d.SAVEDOCUMENTFLAGS_0,1030178)
        


if __name__=='__main__':
    main()
