Considering this thread it looks like getting points selection order is not trivial task for c4d api.

I want to mirror a polygon selection along specified modeling axis, but i'm kinda stuck since i can't apply the dedicated Mirror Tool, the basic Scale Tool also doesn't allow to set the tool settings...

@i_mazlov

The problem with this code - it doesn't always work correctly. Sometimes it's not taking into account selection order - welds to the first selected point for example. Look at this preview.

import c4d

def main():
    doc = c4d.documents.GetActiveDocument()
    op = doc.GetActiveObject()

    lastPoint = op.GetPointS().GetLastElement()

    settings = c4d.BaseContainer()
    settings[c4d.MDATA_WELD_TOPOINT] = True
    settings[c4d.MDATA_WELD_POINTINDEX] = lastPoint
    settings[c4d.MDATA_WELD_OBJECTINDEX] = op
    
    doc.StartUndo()
    doc.AddUndo(c4d.UNDOTYPE_CHANGE, op)
    
    result = c4d.utils.SendModelingCommand(
                    command=c4d.ID_MODELING_WELD_TOOL,
                    list=[op],
                    mode=c4d.MODELINGCOMMANDMODE_POINTSELECTION,
                    bc=settings,
                    doc=doc,)                
    doc.EndUndo()
    c4d.EventAdd()

if __name__=='__main__':
    main()

It works as expected in C4D 2024, but not in the previous versions.

Hello, currently this code welds two points in the middle, but i want it to weld to the last selected point, setting MDATA_WELD_TOPOINT to True doesn't help. How to solve this?

import c4d, sys


#
# M A I N
#
def main():
    doc = c4d.documents.GetActiveDocument()

    settings = c4d.BaseContainer()
    settings[c4d.MDATA_WELD_TOPOINT] = True
    
    result = c4d.utils.SendModelingCommand(
                    command=c4d.ID_MODELING_WELD_TOOL,
                    list=[op],
                    mode=c4d.MODELINGCOMMANDMODE_POINTSELECTION,
                    bc=settings,
                    doc=doc,
                    flags=c4d.MODELINGCOMMANDFLAGS_CREATEUNDO)

    if not result:
        raise RuntimeError(f"Modelling command failed for {op}.")

    # Inform Cinema 4D that the document has been modified.
    c4d.EventAdd()


# Execute main()
if __name__=='__main__':
    main()

Thanks man, i'll take a look at it!

Are there any workarounds for this?

Actually i've got 'Type to search' popup field in C4D 2023.2.0 also, but POPUP_ALLOW_FILTERING flag is omitted.
Is there a way to hide it?

Thanks for your detailed answers, i hoped there is a simpler way to do it)...
Pie menus is a very common thing nowadays, why maxon developers haven't implemented it already?
In modo for example you can create pie menus, popups...etc without any coding.
Not every user is ready/have the time/etc to learn python to build a simple popup, but almost every user needs to customize their working software.
I really hope you'll implement these features soon.

Hi, i'm trying to change Mirror Tool settings, but when i get them using GetActiveToolData() it returns me 'None'. Also i've noticed that changing tool settings in the Attributes tab doesn't show up anything in the Script Log, usually i can see tool setting's name and corresponding value in the log.

Tried both in C4D R26 and 2023.2.0.

Is it a bug or i'm missing something?

Thanks.

import c4d

def main():
    doc = c4d.documents.GetActiveDocument()
    
    c4d.CallCommand(14038) # Mirror
    settings = doc.GetActiveToolData()
    print("settings: %s" % settings)
    
    settings[c4d.MDATA_MIRROR_VALUE] = 0.0
    settings[c4d.MDATA_MIRROR_SYSTEM] = 0

    c4d.EventAdd()

# Execute main()
if __name__=='__main__':
    main()
