Hi Mark,

I am always wary of any model to try and explain the giant constructions at Dahshur.
Like many l have played around with CAD, and come up with some interesting relationships; however, Sneferu's giants are in such a mess, we don't have an accurate data set to work to.
In an ideal world, it would be nice to see site clearance around these giants, similar to what has been achieved at some of the giza giants. This should be followed up by two independent architectural surveys, which should closely agree with each other; especially with the hi-tech kit available these days, to give us an accurate view of both the interior and exterior.
Slowly but surely modern exploration is starting to look at these structures; Frank Monniers recent article, [www.egyptian-architecture.com] only highlights the problems; for example the upper chamber of the Red has less corbels and height than previously reported: now having only 13 corbels and about 1m less in height.
