The ornamental design for a glassbody of a buildingglass, as shown and described.
FIG. 1 is a perspective photographic view of a glass body of a building glass in accordance with my design;
FIG. 2 is an enlarged top photographic view of a surface structure of a portion of the glass body of the building glass of FIG. 1; and,
FIG. 3 is a detailed view of area 3 shown in FIG. 2 of a portion of the glass body of FIG. 2.
The drawings are shown with a symbolic break in length in FIG. 1. In that view, the appearance of any portion beyond the break line forms no part of the claimed design. The broken lines in FIGS. 2 and 3 show the lines upon which the partial views are taken from their respective larger views, and they also form no part of the claimed design.
