Frame Selected Object

I'm trying to render the active object isolated from all other objects of the document.
To do so, from inside my plugin, I created a new document, created a clone of the intended object and inserted it in the new document. Then I performed a render of that object and finally, get rid of that document.
It all works fine, except that I can't seem to perform a "Frame Selected Object" on the object that is inside the new document. When I run that command, the current object, still in my current object gets framed.
I'm using this code:doc = documents.GetActiveDocument()
new_doc=c4d.documents.BaseDocument()
rd = new_doc.GetActiveRenderData().GetData()
new_tree=node.GetClone()
new_doc.InsertObject(new_tree)
xres = 128
yres = 128
bmp = bitmaps.BaseBitmap()
bmp.Init(x=xres, y=yres, depth=24)
rd[c4d.RDATA_XRES]=xres
rd[c4d.RDATA_YRES]=yres
new_doc.SetSelection(new_tree,c4d.SELECTION_NEW)
c4d.CallCommand(12151) # Frame Selected Objects
res = documents.RenderDocument(new_doc, rd, bmp, c4d.RENDERFLAGS_EXTERNAL)
if res==c4d.RENDERRESULT_OK:
bitmaps.ShowBitmap(bmp)
new_doc.Flush()How can I frame just the cloned object, inside the new document?

How do you think the CallCommand would know that it should use your
new document? It operates always on the active scene only.-Niklas

I thought it would operate like how you say, but I tried the "shot in the dark" of selecting the newly inserted object and hopped that it would affect the last selected object ;-)
So, it must be made by hand, adjusting the virtual camera of the new document?
Does anyone now how to calculate the placement and orientation of the camera to frame an object?

You didn't make the new_doc the current document. ;)
Insert it and make it the active document.

Thank you, Niklas. It worked!!!
However, the object is not being framed correctly.
My code is this:doc = documents.GetActiveDocument()
new_doc=c4d.documents.BaseDocument()
rd = new_doc.GetActiveRenderData()
rdc = rd.GetData()
new_tree=node.GetClone()
new_doc.InsertObject(new_tree)
xres = 256
yres = 256
bmp = bitmaps.BaseBitmap()
bmp.Init(x=xres, y=yres, depth=24)
rdc[c4d.RDATA_XRES]=xres
rdc[c4d.RDATA_YRES]=yres
rd.SetData(rdc)
c4d.documents.SetActiveDocument(new_doc)
new_doc.SetActiveRenderData(rd)
c4d.EventAdd(c4d.EVENT_FORCEREDRAW)
new_doc.SetSelection(new_tree,c4d.SELECTION_NEW)
c4d.CallCommand(12151) # Frame Selected Objects
res = documents.RenderDocument(new_doc, rdc, bmp, c4d.RENDERFLAGS_EXTERNAL)
c4d.documents.SetActiveDocument(doc)
if res==c4d.RENDERRESULT_OK:
bitmaps.ShowBitmap(bmp)
new_doc.Flush()The render shows a clipped object :-(

Already tried with:
c4d.CallCommand(12148) # Frame Geometry
and with
c4d.CallCommand(12288) # Frame All
To no avail :-(

Ok, never mind. I created my own framing code. It works for what I need.
