Hi,

there seems to be an issue with c4d.utils.SendModelingCommand() using MCOMMAND_JOIN as command ID in Release 18.048.

import c4d
from c4d import gui
#Welcome to the world of Python
  
def main() :
    
    olist = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_0)   
    settings = c4d.BaseContainer()                 # Settings    
    res = c4d.utils.SendModelingCommand(command = c4d.MCOMMAND_JOIN,
                                        list = olist,
                                        bc = settings,
                                        doc = doc)
                                    
    doc.InsertObject(res[0].GetClone())    
    c4d.EventAdd()
    
    
if __name__=='__main__':
    main()

While with Release 17 the results are as expected. SMC connects all selected objects.
In R18.028 the result contains only one object of the selected object.

Hi Peter,

For MCOMMAND_JOIN to always work the objects to join must be children of a parent object, a null for instance.
Pass the list argument as [null] with null the parent null object variable.

The command worked pre-R18 with multi-selection of objects but now the objects to join have to be arranged under a parent object.

Hi Yannick,

thank you for your explanation. I'll give it a try.
Are there other Modeling IDs with a different behavior in R18?
