  We consider three-dimensional reshaping of thin nemato-elastic sheets
containing half-charged defects upon nematic-isotropic transition. Gaussian
curvature, that can be evaluated analytically when the nematic texture is
known, differs from zero in the entire domain and has a dipole or hexapole
singularity, respectively, at defects of positive or negative sign. The latter
kind of defects appears in not simply connected domains. Three-dimensional
shapes dependent on boundary anchoring are obtained with the help of finite
element computations.
