Ronan,
There is a cast function. But the syntax isn't much shorter.
import comtypes
import comtypes.gen.AutoCAD as ACAD
app = comtypes.client.GetActiveObject("AutoCAD.Application")
obj = app.ActiveDocument.ModelSpace(1)
#Assume this obj is a block
block = comtypes.cast(obj, comtypes.POINTER(ACAD.IAcadBlockReference))
# I hope this would work
# block = comtypes.cast(obj, ACAD.IAcadBlockReference)
print "Layer name: %s" % block.Layer
print "Color: %d" % block.Color
print block.InsertionPoint
print block.XScaleFactor
But I'm getting error when trying to access various block properties. See output
below. Apparently it was OK to access the "Layer" and "Color" properties. Don't
know why. Waiting for Thomas...
Thanks.

Layer name: 0
