Fairgate's Omnigraph Multi-Function Template is an extremely versatile tool for designers, artists, hobbyists, or anyone who enjoys drawing. The OmniGraph combines the functions of several traditional drawing instruments in a single template. A mechanical pencil and Fairgate's OmniGraph are all that is needed to create a wide range of highly accurate shapes, including circles, squares, polygons of 5, 6, 8, 9, 10, 12, 16, and 18 sides, and much more. Like all Fairgate instruments, the OmniGraph is ruggedly built to provide years of reliable service. Instructions for use are included with each OmniGraph, but to truly appreciate this unique tool, you must try it, its versatility is limited only by your imagination.
