#### Abstract

For a special class of Young functions, the
Sobolev-Orlicz capacity is estimated from below by the
*(n-m)*-dimensional Hausdorff content. The proof is based on
pointwise estimates of superminimizers of the Orlicz type Dirichlet
integrals. As a consequence we derive a sharp answer to the question
which Sobolev functions have Lebesgue points
*H*^{n-m}-a.e. and serve as good transformations for the
coarea change of variables.
