This is a font imitating the stage of outline construction of letters using drawing tools - compass and ruler. It is very geometric (with auxiliary lines, axes, centers of circles, tangents, and conjugation of circles), although the circles are somewhat compressed from four sides. The second style, which plays the role of Bold style, is a hatched version of the Regular style.
The font has very small elements that appear in a sufficiently large size, so it is better to use it for large compositions, in particular, advertisements, posters, large headings, etc.
The family is named “Khachatur” after the name of the father of designer Ruben Tarumian — architect Khachatur Hakobyan, his first master.
