ABSTRACT OF THE DISCLOSURE A template aid for draftsmen which makes it simple to crosshatch in section and to provide lettering guide lines. The template aid includes an equilateral polygon- shaped sheet having "x" straight-edged sides wherein "x" is an integer larger than 2, and a plurality of equilateral polygon-shaped openings formed in the sheet, each opening having "yx" straight-edged sides where y is a positive integer. The openings are disposed with respect to the sheet straight-edged sides so that for each opening there is a line perpendicular to a straight-edged side of the sheet that bisects an apex of the opening. The plurality of openings are disposed in at least one series, in each series the distance from the apex of each opening to a corresponding apex in an adjacent opening being a constant throughout the series, relative to a given straight edge of the sheet.
