Hi, I want to store a Pointsselection and later restore that Selection on another Identical Object.
I tried this...but with no luck
points = obj.GetPointS()
count = NewObj.GetPointCount()
newPoints = NewObj.GetPointS()
newPoints.DeselectAll()
for i in xrange(count) :
if points.IsSelected(i) :
newPoints.Select(i)

Hi Holgar,
You can simply use BaseSelect.CopyTo() to copy a selection to another. Note you have to send a MSG_UPDATE after changing the selection:
sel = obj.GetPointS()
otherSel = newObj.GetPointS()
sel.CopyTo(otherSel)
newObj.Message(c4d.MSG_UPDATE)

Thanks Yannick. But it does not work for me. What I do is I make CallCommand with Shrinkselection and than I want to restore the old selection. Its not working.

Just some question:
selobj=doc.GetSelection()
Why dont you use doc.GetActiveObject() or doc.GetActiveObjects?
You just wanna work with Objects, rigth?
obj.Message(c4d.MSG_UPDATE)
Why do you send this message befor the selection change?
c4d.CallCommand(12559) # Shrink Selection
Isnt it more comfortable to use
c4d.utils.SendModelingCommand(command = c4d.MCOMMAND_SELECTSHRINK,
list = [selobj],
mode = c4d.MODELINGCOMMANDMODE_POINTSELECTION,
bc = c4d.BaseContainer(),
doc = doc)
Ok, in this case selobj is the active object in any cases.
And finally just to clearify:
- you store the selection of an object
- you shrink the selection
- you create and insert a clone of the object with the shrinked selection
- you put the unshrinked selection at the clone and remove the object
Where is the difference before and after the script?

This is just an example copied from a script. I store the selection before I shrink the selection. So I would expect i can restore it later from the state before I shrink it. But I guess something is wrong with my logic.

Ok, I understand.
I think sel isnt an instance or clone of obj.GetPointS(), so you change sel with SELECTSHRINK, too.

obj = doc.GetActiveObject()

newobj = obj.GetClone()
newobj.InsertAfter(obj)
newobj.SetRelPos(c4d.Vector(0,0,200))
