  We have computed theoretical models of circumstellar disks for the classical
Be stars $\kappa$ Dra, $\beta$ Psc, and $\upsilon$ Cyg. Models were constructed
using a non-LTE radiative transfer code developed by \citet{sig07} which
incorporates a number of improvements over previous treatments of the disk
thermal structure, including a realistic chemical composition. Our models are
constrained by direct comparison with long baseline optical interferometric
observations of the H$\alpha$ emitting regions and by contemporaneous H$\alpha$
line profiles. Detailed comparisons of our predictions with H$\alpha$
interferometry and spectroscopy place very tight constraints on the density
distributions for these circumstellar disks.
