Вы уже за столом, а у нас рабочее время... А Startrek в Сиэттле, наверное, проснулся недавно... Про эллипс здесь: http://autokad.ru/forum/viewtopic.php?t=522 Про spline to pline тоже где-то здесь на форуме.
Админ: про Поиск здесь говорили. Не получилось найти ни по слову Эллипс, ни по слову PELLIPSE, которое я взял оттуда как ключевое |
