A box type is an n-type of an o-minimal structure which is
uniquely determined by the projections to the coordinate axes.
We characterize heirs of box types
of a polynomially bounded o-minimal structure M. From this,
we deduce various structure theorems
for subsets of Mk, definable in the expansion ℳ of M by all
convex subsets of the line. We show that ℳ after naming constants,
is model complete provided M is model complete.
