Knife Modeling Command

I'm using SendModelingCommand() to apply the Knife Tool to some objects. But it does not seem like the
modeling command supports all the options the actual Knife Tool does. For instance, I can not activate the
generation of N-Gons, only cutting visible polygons or any but the "Line" mode.

Check out the scene here. You can move the "Cut_Plane" around to change the cut position, and at some
positions it creats NGons. Even if you activate the "NGons" option, it still creates NGons.

The code I use to cut the object is

def cut(obj, p1, p2, n1, n2, options={}) :
    data = c4d.BaseContainer()
    data.SetVector(c4d.MDATA_KNIFE_P1, p1)
    data.SetVector(c4d.MDATA_KNIFE_P2, p2)
    data.SetVector(c4d.MDATA_KNIFE_V1, n1)
    data.SetVector(c4d.MDATA_KNIFE_V2, n2)
    data.SetBool(c4d.MDATA_KNIFE_NGONS, bool(options.get('ngons')))
    data.SetBool(c4d.MDATA_KNIFE_VISIBLEONLY, bool(options.get('visible_only')))
    c4d.utils.SendModelingCommand(
        c4d.MCOMMAND_KNIFE, [obj], bc=data, doc=obj.GetDocument())

Can I enabled NGons and Visible Only somehow?

Thanks

Edit : By the way, here's a nice post from Yannick with details about cutting.

Hello,

you are using the Knife command (MCOMMAND_KNIFE). The parameters you want to enable are parameters of the Knife tool (ID_MODELING_KNIFE_TOOL). Unfortunately this tool does not support  the usage of SendModellingCommand. The docs will be updated.

Best wishes,
Sebastian

Hi Sebastian, thanks for the reply.
Since the prefix of the symbols that need to be used (P1, P2, V1, V2),
is the same as the other knife tool symbols, I thought it might work
somehow. Unfortunate it does not 😞

Best
