c4d.utils.SendModelingCommand(command, list, mode=MODELINGCOMMANDMODE_ALL, bc=None, doc=None, flags=MODELINGCOMMANDFLAGS_NONE)¶ - With this function one can apply nearly all modeling commands.The function is applied to the objects in list. With the parameter mode you can decide if the current selection should be used to control what points/polygons are affected.
Note
Current State to Object(CSTO) has to be executed on a duplicate of an object because CSTO modifies the existing caches.In some cases you have to use a temporary document as wellObjectData.GetVirtualObjects().This is a small example how you can use this function
import c4d from c4d import utils settings = c4d.BaseContainer() # Settings settings[c4d.MDATA_EXTRUDE_OFFSET] = 50.0 # Length of the extrusion res = utils.SendModelingCommand(command=c4d.ID_MODELING_EXTRUDE_TOOL, list=[op], mode=c4d.MODELINGCOMMANDMODE_POLYGONSELECTION, bc=settings, doc=doc) c4d.EventAdd() if res is False: print "Something went wrong." elif res is True: print "Command successful." elif isinstance(res, list): print "Here you get the newly created object(s)."
