If you have a point symmetry, e.g. icosahedral symmetry, Chimera has no way to extract a wedge of density that is one asymmetric unit. If you have an atomic model of an asymmetric unit fit into the density, you could extract a box around it using Chimera volume viewer menu entry Features / Atom Box. Or you could extract the density just at grid points within a specified distance of atoms using volume viewer menu entry Features / Zone…. To save the results of either of those methods use volume viewer menu File / Save Map As….
