ABSTRACT:
A drawing template for facilitating the formation of images upon a spherical surface is disclosed. In a first embodiment the template comprises first and second transparent hollow hemispheres having indicia formed upon their surfaces such that the two hemispheres may be disposed about a spherical drawing surface and the indicia may then be used as a guide to form corresponding images upon the drawing surface. In a second embodiment, a planar sheet of flexible material is configured such that it will conform substantially to the shape of a sphere when placed in laminar juxtaposition therewith. Indicia formed upon the sheet of flexible material provide a guide by which images may be formed upon the drawing surface. Both embodiments of the drawing template of the present invention are particularly applicable for use with a three-dimensional drawing device which forms images upon the inner surface of a transparent sphere.
