Hi.

I'm having trouble with doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op).
After executing the code, c4d jumps 2 Steps backwards, and not 1, clicking on Undo.

            original    = op.GetPointS()  
          doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op)  
          point_sel.CopyTo(original)

Any Idea ?

Cheers, nux

Of course, sorry.

  
import c4d  
  
  
sel = c4d.BaseSelect()  
doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op)  
sel.CopyTo(op.GetPolygonS())  
  
c4d.EventAdd()

1. Create a Polygonobject.
2. Select some Polys
3. Again select some other Polys
4. Execute the script
5. Do undo

And you'll see the first polygon selection, not the second you've done.

//edit:
I think I could figure out the issue, let me just try that.
(Start/EndUndo missing)

Hm, this code works:

  
import c4d  
  
  
sel = c4d.BaseSelect()  
doc.StartUndo()  
doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op)  
sel.CopyTo(op.GetPolygonS())  
doc.EndUndo()  
  
c4d.EventAdd()

But i just don't get it to work in my plugin.
In this case it just copys a selection to the corresponding selection for the mode.

        doc.StartUndo()  
      if mode     == c4d.Mpoints:  
          doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op)  
          point_sel.CopyTo(op.GetPointS())  
      elif mode   == c4d.Mpolygons:  
          doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op)  
          poly_sel.CopyTo(op.GetPolygonS())  
      elif mode   == c4d.Medges:  
          point_sel_cache     = op.GetPointS().GetClone()     #Save the current pointselection  
          doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op)  
          point_sel.CopyTo(op.GetPointS())                    #Copy Pointselection to Object  
  
          bc      = c4d.BaseContainer()                       #BaseContainer holding Data for MC  
          bc[c4d.MDATA_CONVERTSELECTION_LEFT]     = 0         #Convert Points  
          bc[c4d.MDATA_CONVERTSELECTION_RIGHT]    = 1         #to Edges  
          bc[c4d.MDATA_CONVERTSELECTION_TOLERANT] = False     #Tolerance gives wrong results  
          bc[c4d.SELECTION_NEW]                   = True  
  
          doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op)  
          SendModelingCommand(        command     = c4d.MCOMMAND_CONVERTSELECTION,  
                                      list        = [op],  
                                      doc         = op.GetDocument(),  
                                      bc          = bc  
                              )  
  
          doc.AddUndo(c4d.UNDOTYPE_CHANGE_SELECTION,op)  
          point_sel_cache.CopyTo(op.GetPointS())              #Restore Pointselection Cache  
  
      doc.EndUndo()

What undo-stuff did i miss here ?

The code seems to be fine. I can't explain the behave yet.
