положение осей изометрической проекции показано на рис. 85, г. оси х и у располагают под углом 30° к горизонтальной линии (угол 120° между осями). построение осей удобно проводить при угольника с углами 30, 60 и 90°
чтобы построить оси изометрической проекции с циркуля, надо провести ось z, описать из точки о дугу произвольного радиуса; не меняя раствора циркуля, из точки пересечения дуги и оси z сделать засечки на дуге, соединить полученные точки с точкой о.
при построении фронтальной диметрической проекции по осям х и z (и параллельно им) откладывают действительные размеры; по оси у (и параллельно ей) размеры сокращают в 2 раза, отсюда и название "диметрия", что по-гречески означает "двойное измерение".
