Thanks Markus, For now this capability seems to be 'missing'. Once again I'm left wishing I was a competent c/c++ programmer (wip...). In any event, I suspect this approach has been mostly (?) superseded by 'Structure from Motion' type modelling which I'm also playing with- was just hoping to be able to add 'traditional' photogrammetric modelling to my toolkit and be able to do a comparison between the two).
